Abstract: A safety switch is disclosed herein. The safety switch may comprise: a housing, wherein the housing comprises a mating cam; a face plate, wherein the face plate is coupled to the housing; and a subassembly coupled to the face plate, wherein the subassembly comprises: a base, wherein the base comprises a slot; a cam, wherein the cam is positioned within the base; a pushbutton, wherein the pushbutton comprises a hole; and a pin positioned through the hole of the pushbutton and the slot of the base; wherein the cam, the base, and the pushbutton are mated together with the pin; wherein the subassembly is not rotatable due to the pin.

Abstract: Embodiments relate generally to systems and methods for actuating a safety switch, particularly by converting a linear force to a rotary motion. A safety switch may comprise: a housing, wherein the housing comprises a mating cam; a face plate, wherein the face plate is coupled to the housing; and a subassembly coupled to the face plate, wherein the subassembly comprises: a base, wherein the base comprises a slot; a cam, wherein the cam is positioned within the base; a pushbutton, wherein the pushbutton comprises a hole; and a pin positioned through the hole of the pushbutton and the slot of the base; wherein the cam, the base, and the pushbutton are mated together with the pin; wherein the subassembly is not rotatable due to the pin.

Abstract: A switch assembly includes an M-blade snap spring, an actuation arm, and a switch. The M-blade snap spring exhibits snap-action movement between a first actuator position and a second actuator position. The switch is responsive to the snap-action movement of the M-blade to move between a first switch position and a second switch position. The actuation arm is configured to selectively cause the M-blade snap spring to move, via snap-action, between the first actuator position and the second actuator position, which in turn causes the switch to move between the first switch position and the second switch position, respectively.

Abstract: A snap-action switch includes an M-blade snap spring, an actuation arm, a first bridge, and a second bridge. The M-blade snap spring includes a closed end, a double-loop end, a first outer leg, a second outer leg, a first inner leg, a second inner leg, and a cross member. The actuation arm is coupled to the first and second inner legs, and distorts the M-blade snap to exhibit snap-action movement between a first switch position and a second switch position. When the M-blade snap spring is in the first switch position, the double-loop end engages the first bridge and does not engage the second bridge, and when the M-blade snap spring is in the second switch position, the double-loop end engages the second bridge and does not engage the first bridge.

Abstract: A microwave door interlock switch system and method includes the use of a primary switch and a monitor switch capable of being actuated in sequence via an actuating lever. The primary switch is associated with a primary control circuit that controls the operation of a magnetron associated with a microwave device, while the monitor switch can function as a monitor for verifying the correct state of the primary switch. The interlock switch system can further include a mounting bracket, a base mounting bracket and a compression spring and an adjustment screw. The compression spring adjustment mechanism allows an assembler of the microwave device to fine-tune the location of the interlock switch system during assembly of the microwave device. The switch actuation can be set to occur at a precise point of door closure.
