An interlock switch used with an electrical appliance such as a microwave oven. The interlock switch includes a cantilevered common switch element, and two other switch elements mounted on opposite sides of the common switch elements. When the appliance door is closed, the common switch element makes contact with the switch elements on one side and breaks contact with the switch element on the other side.

Electrical appliance interlock switch

An interlock switch used with an electrical appliance such as a microwave oven. The interlock switch comprises a housing having a plurality of conductive swtich elements operated by an actuator. At least two of the conductive switch elements are biased in opposite directions, thereby reducing the force that would otherwise be needed to operate the actuator.

Electrical appliance interlock switch with force efficient actuator

A tactile feedback switch having a contactor element having a curvilinear portion which temporarily changes from a substantially convex shape to a substantially concave shape upon movement of the contactor element into engagement with an electrical contact. An indentation in the contactor element reduces the force otherwise needed to be applied to the top portion of the contactor element in order to maintain the contactor element in engagement with the electrical contact.

Tactile feedback switch

A panel mounted switch consisting of two complementary side sections housing the switch components that include a plunger-type actuator carrying two movable switch blades and a series of fixed terminals. The switch blades being yieldably connected to the actuator whereby they are free to rock about their longitudinal axis upon engagement with certain of said fixed terminals, thereby achieving a self-cleaning, wiping switching contact.
