diaphragm through which passes an actuating member H01H13/08Casing of switch constituted by a handle serving a purpose other than the actuation of the switch H01H13/10Bases Stationary contacts mounted thereon H01H13/12Movable parts Contacts mounted thereon H01H13/14Operating parts H01H13/16adapted for operation by a part of the human body other than the hand H01H13/18adapted for actuation at a limit or other predetermined position in the path of a body, the relative movement of switch and body being primarily for a purpose other than the actuation of the switch H01H13/183for actuation by moving a closing member H01H13/186wherein the pushbutton is rectilinearly actuated by a lever pivoting on the housing of the switch H01H13/20Driving mechanisms H01H13/22acting with snap action H01H13/24with means for introducing a predetermined time delay H01H13/26Snap-action arrangements depending upon deformation of elastic members H01H13/28using compression or extension of coil springs H01H13/285having a symmetrical configuration H01H13/30one end of spring transmitting movement to the contact member when the other end is moved by the operating part H01H13/32one end of spring being fixedly connected to the stationary or movable part of the switch and the other end reacting with a movable or stationary member respectively through pins, cams, toothed or other shaped surfaces H01H13/34having two or more snap-action motions in succession H01H13/36using flexing of blade springs H01H13/365having a symmetrical configuration H01H13/38Single blade moved across dead-centre position H01H13/40Blade spring with at least one snap-acting leg and at least one separate contact-carrying or contact-actuating leg H01H13/42having three legs H01H13/44having two or more snap-action motions in succession H01H13/46two separate blade springs forming a toggle H01H13/48using buckling of disc springs H01H13/50having a single operating member H01H13/503Stacked switches H01H13/506with a make-break action in a single operation H01H13/52the contact returning to its original state immediately upon removal of operating force H01H13/54the contact returning to its original state a predetermined time interval after removal of operating force H01H13/56the contact returning to its original state upon the next application of operating force H01H13/562making use of a heart shaped cam H01H13/564convertible to momentary push button switches H01H13/568the contact also returning by some external action H01H13/58with contact-driving member rotated step-wise in one direction H01H13/585wherein the movable contact rotates around the axis of the push button H01H13/60with contact-driving member moved alternately in opposite directions H01H13/62the contact returning to its original state upon manual release of a latch H01H13/64wherein the switch has more than two electrically distinguishable positions H01H13/66the operating member having only two positions H01H13/68having two operating members, one for opening and one for closing the same set of contacts H01H13/70having a plurality of operating members associated with different sets of contacts H01H13/7006comprising a separate movable contact element for each switch site, all other elements being integrated in layers H01H13/7013in which the movable contacts of each switch site or of a row of switch sites are formed in a single plate H01H13/702with contacts carried by or formed from layers in a multilayer structure H01H13/703characterised by spacers between contact carrying layers H01H13/704characterised by the layers H01H13/705characterised by construction, mounting or arrangement of operating parts H01H13/7057characterised by the arrangement of operating parts in relation to each other H01H13/7065characterised by the mechanism between keys and layered keyboards H01H13/7073characterised by springs H01H13/72wherein the switch has means for limiting the number of operating members that can concurrently be in the actuated position H01H13/74each contact set returning to its original state only upon actuation of another of the operating members H01H13/76wherein some or all of the operating members actuate different combinations of the contact sets H01H13/78characterised by the contacts or the contact sites H01H13/785characterised by the material of the contacts
