The invention relates to a mechanical switch, in particular a light switch and/or roller shutter switch and/or thermostat switch. The invention further relates to an electromechanical actuator unit for such a mechanical switch, a switch arrangement comprising such a mechanical switch and such an electromechanical actuation unit and a method for controlling a switch.
Mechanical switches of the type mentioned above are known from the area of electrical installation. When a user is to be provided with further functions, in particular electromechanical functions such as for example enabling the actuation of the switch from afar, the switch must normally be replaced with a switch with such a functionality. Examples of such switches are for example known from CN 202 871 661 U and DE 10 2015 010 820 A1.
It is the task of the present invention to provide a mechanical switch that can be extended by further functions (plug and play) in a simple way, i.e. without additional wiring effort.
To solve this task a mechanical switch of the type mentioned above is suggested, which comprises a switching contact assembly, in particular a monostable, bistable or tristable switching contact assembly and a base carrier, in which the switching contact assembly is received. The base carrier further comprises a guide means. The mechanical switch comprises an operating mechanism, which is guided in the guide means and is suitable for adopting an operating position following external mechanical action for effecting a state change of the switching contact assembly, and takes up a resting position in the absence of the external mechanical action. The base carrier further has a holding device for receiving an electromechanical actuator unit, wherein the holding device is designed in such a way that an electromechanical actuator unit received in the holding device can be supplied with voltage to effect a state change of the switching contact assembly by means of the electromechanical actuator unit independently of an external mechanical action on the operating mechanism.
This design allows the mechanical switch to be equipped with an actuator unit in a simple way, for example to effect a state change in the switching contact assembly from a distance.
The holding device preferably comprises a first plug-in connection means, which can be connected with a second plug-in connection means of the electromechanical actuator unit for supplying the electromechanical actuator unit received in the holding device with voltage, wherein the first plug-in connection means is preferably designed as a socket and the second plug-in connection means as a plug.
This design allows a simple connection of the actuator unit with the holding device for supplying the electromechanical actuator unit with voltage.
According to the invention the switching contact assembly is uncoupled from the operating mechanism when the operating mechanism adopts the resting position.
This design allows to effect a state change of the switching contact assembly by means of the electromechanical actuator unit in a simple way.
The guide means preferably has at least one linear guide element for a linear guiding of the operating mechanism and/or at least one rotary guide element for the rotatable guiding of the operating mechanism, wherein the linear guide element is further preferably designed as a slot open on one side or as an elongated hole and/or the rotational guide element is designed as an opening or blind hole with respective circular cross-sections.
This design allows the use different operating mechanisms for the mechanical switch.
In a preferred design the switching contact assembly has at least one rocker switch rotatably mounted in the base carrier and at least one first switching contact, wherein the rocker switch is suitable for adopting a first position, in which the rocker switch touches the first switching contact, and at least one neutral position, in which the rocker switch is located at a distance from the first switching contact.
The base carrier preferably comprises a guide arrangement and the switching contact assembly has a carriage that is mounted to move along and/or against a guiding direction in the guide arrangement, wherein the carriage is preferably suitable for adopting a neutral position, in which the carriage is mechanically uncoupled from the rocker switch.
This design further allows the mechanical switch to be operated by means of the operating mechanism even if an electromechanical actuator unit is received in the holding device.
In a preferred design the mechanical switch comprises at least one spring element, which is connected on the base carrier and the carriage in such a way that the spring element applies a force to the carriage, with which the carriage can be transferred from a first switching position and/or a second switching position and/or a first interim position and/or a second interim position into the neutral position.
The carriage preferably has a first target surface that is suitable for being brought into contact with a first tappet of a first actuator of the electromechanical actuator unit received in the holding device for moving the carriage along guide direction and effecting a state change of the switching contact assembly in this way.
In a preferred design the carriage has a second target surface, which is suitable for being brought into contact with a second tappet of a second actuator of the electromechanical actuator unit received in the holding device for displacing the carriage along guide direction and to effect a state change of the switching contact assembly in this way.
The first target surface and the second target surface are preferably designed in such a way that a successive movement of the first tappet and the second tappet effects a movement of the carriage from the neutral position into a first switching position.
A transfer of the switching contact assembly into the first switching condition is preferably effected during a movement of the carriage from the neutral position into the first switching position. The previously mentioned designs allow a reduction of the forces to be applied on the carriage by the electromechanical actuator unit for effecting a state change of the switching contact assembly.
In a preferred design the carriage has a third target surface, which is suitable for being brought into contact with the first tappet of the first actuator of the electromechanical actuator unit received in the holding device for moving the carriage against guide direction and thus effect a state change of the switching contact assembly.
The carriage preferably has a fourth target surface, which is suitable for being brought into contact with the second tappet of the second actuator of the electromechanical actuator unit received in the holding device for displacing the carriage against guide direction and thus effect a state change of the switching contact assembly.
In a preferred design the third target surface and the fourth target surface are designed in such a way that a successive movement of the second tappet and the first tappet effects a movement of the carriage from the neutral position into a second switching position.
These designs allow the switching mechanism to be transferred into a second switching position by means of the carriage and the electromechanical actuator unit when the carriage is moved from the neutral position into the second switching position.
An arrangement of the target surfaces described above determines the movement of the carriage, starting from neutral position, either in guide direction or against guide direction through the sequence of actuating the actuators. If the first actuator is actuated first and the second actuator second based on the neutral position of the carriage, this results in a movement of the carriage in guide direction into the first switching position, which transfers the switching contact assembly into the first switching position. If the second actuator is actuated first and the first actuator second based on the neutral position of the carriage, this results in a movement of the carriage against guide direction into the second switching position, which transfers the switching contact assembly into the second switching position.
The first target surface is preferably received at an oblique angle in relation to a movement direction of the first tappet of the electromechanical actuator unit received in the holding device and/or the second target surface is received at an oblique angle in relation to a movement direction of the second tappet of the electromechanical actuator unit received in the holding device and/or the third target surface is received at an oblique angle in relation to a movement direction of the first tappet of the electromechanical actuator unit received in the holding device and/or the fourth target surface is received at an oblique angle in relation to a movement direction of the second tappet of the electromechanical actuator unit received in the holding device.

The first arresting means is preferably designed in such a way here that the head of the first tappet is held in the first arresting direction even when the first actuator is not powered up.
The first target surface, the second target surface and the first arresting means are preferably arranged and designed in such a way that a movement of the head of the first tappet up to the first arresting means effects a movement of the carriage from the neutral position into the first interim position, and a movement of the second tappet following this effects a disconnection of the connection between the head of the first tappet and the first arresting means and a movement of the carriage from the first interim position into a first switching position. The first arresting means is still preferably designed in such a way here that the first tappet of the non-powered first actuator is disconnected from the first arresting means when the carriage is transferred from the first interim position into the first switching position, which retracts the first tappet against the first movement direction.
A movement of the carriage from the first interim position into the first switching position preferably effects that the switching contact assembly adopts the first switching position.
In a preferred design the carriage comprises a second arresting means neighbouring the fourth target surface, which can be connected with a head of the second tappet for holding the carriage in a second interim position, wherein the second arresting means is arranged in such a way that the head of the second tappet is suitable for sliding along the fourth target surface up to the second arresting means for connecting the head of the second tappet with the second arresting means in the second interim position. The second arresting means is preferably designed in such a way here that the head of the second tappet in held in the second arresting means even when the second actuator is not powered up.
The fourth target surface, the third target surface and the second arresting means are preferably arranged and designed in such a way that a movement of the head of the second tappet up to the second arresting position effects a movement of the carriage from then neutral position into the second interim position, and a movement of the first tappet following this effects a disconnection of the connection between the head of the second tappet and the second arresting means and a movement of the carriage from the second interim position into a second switching position. The second arresting means is further preferably designed in such a way here that the second tappet of the non-powered second actuator is disconnected from the second arresting means when the carriage is transferred from the second interim position into the second switching position, which retracts the second tappet against the second movement direction.

The second tilt position can be arranged between the second switching position SP2 and the neutral position NP. The first tilt position and the second tilt position can each constitute a tilt point of the rocker switch 22. The spring means transfers the rocker switch 22 into the first switching position here when the rocker switch adopts a position between the first tilt position and the first switching position. The second tilt position can preferably constitute a tilt point of the rocker switch, so that the spring means transfers the rocker switch 22 into the second switching position SP2 when the rocker switch 22 adopts a position between the first tilt position and the second switching position SP2. The carriage 26 can be designed to transfer the rocker switch 22 from the neutral position NP in the direction of the first switching position SP1 and further than the first tilt position here when the carriage is moved from the neutral position N into the first tilt position S1. The carriage 26 can further be suitable for transferring the rocker switch 22 from the neutral position in the direction of the second switching position SP2 and further than the second tilt position when the carriage 26 is moved from the neutral position N into a second switching position S2.

The second interim position Z2 is for example reproduced in
In the first interim position Z1 the first actuator 120 can be deactivated, so that the first tappet 122 is moved against the movement direction M1 of the first tappet 122 when the head 123 of the first tappet 122 leaves the first arresting means 21.
In the second interim position Z2 the second actuator 130 can be deactivated in the same way, so that the tappet 132 is moved against the movement direction M2 of the second tappet 132 when the head 133 of the second tappet 132 leaves the second arresting means 21a.
The first target surface 30, the second target surface 32 and the first arresting means 21 are preferably arranged and designed in such a way that a movement of the head 123 of the first tappet 122 effects a movement of the carriage 26 from the neutral position N to interim position Z1 and a movement of the second tappet 132 following the same effects a disconnection of the connection between the head 123 of the first tappet 122 and the first arresting means 21, and a movement of the carriage 26 from the first interim position Z1 to the first switching position S1 is effected.
