Claims
- 1. A method for making a circuit interrupter device comprising the steps of blanking a pair of terminals from a flat metal strip in selected spaced relation to each other and blanking carrier portions of the strip connected to the terminals for temporarily maintaining the terminals in said spaced relation, molding an electrically insulating housing around the terminals including a first housing side having selected portions of the terminals embedded therein so that respective side surfaces of the embedded terminal portions are exposed from the housing material at said one housing side and including a second housing side adjacent said one housing side having ends of the respective terminals extending through said second housing side, securing first contact means to the exposed side surface of the embedded portion of one of the terminals, securing a thermostat metal element having movable contact means thereon to the exposed side surface of the embedded portion of the other of said terminals so that the thermostat metal element extends closely along said one housing side for moving the movable contact means into and out of engagement with the first contact means in response to occurrence of selected thermostat element temperatures, and blanking the carrier portions of the flat metal strip from the terminals to leave the terminals supported in the housing material molded thereon.
- 2. A method according to claim 1 wherein a lid is secured to the molded housing material in closely overlying relation to the thermostat metal element.
- 3. A method according to claim 2 wherein the thermostat metal element has a relatively long and narrow projection weld means thereon adjacent one end thereof and has said movable contact means mounted at an opposite end of the thermostat metal element, the projection weld is engaged with the exposed side surface of the embedded portion of said other terminal with the projection extending along a line of engagement with the length of the embedded terminal portion, the thermostat metal element is rotated around that line of engagement for engaging the movable contact means with the first contact means with selected contact force, and the thermostat metal element is resistance welded to the other terminal along said line of engagement for securing the thermostat element in position with that desired contact force.
- 4. A method according to claim 2, wherein the housing is molded to have a key-shaped slot in a side thereof adjacent the embedded portion of said other terminal, the thermostat metal element has a key-shaped tang extending from said one end thereof and the tang is movably disposed in said key-shaped slot for selectively positioning the thermostat metal element with said weld projection extending along a selected part of the length of the embedded portion of the other terminal prior to welding of the thermostat metal element to said other terminal.
- 5. A method for making a condition responsive device comprising the steps of providing a pair of elements in spaced relation on a base, securing first contact means to one of the base elements, providing a thermostat metal element having movable contact means at one end and having a relatively long and narrow projection weld means thereon adjacent an opposite end thereof, engaging said projection weld means with the other base element with the projection weld means extending along a line of engagement with the other base element and rotating the thermostat metal element around that line of engagement for engaging the movable contact means with the first contact means with selected contact force, and resistance welding the thermostat metal element to the other base element along said line of engagement for securing the thermostat element to that other element to move the movable contact means into and out of engagement with the first contact means in response to occurrence of selected thermostat element temperatures.
