Abstract: A switch includes a printed circuit board and a contact piece with first and second contacts. The printed circuit board has a power input contact, a power output contact, a noncontact area, and a plurality of signal contacts that are disposed at a plurality of predetermined positions. The power input contact and the plurality of signal contacts are disposed on the printed circuit board such that, upon movement of the first contact from the noncontact area to a signal contact, the second contact will align with the power input contact prior to the first contact aligning with the signal contact.

Abstract: A reversely mountable tactile switch assembly has a switch housing with switch terminals and an actuator button secured thereto on the same side of the housing, and can be used on a printed circuit board. The resulting printed circuit board provides for smaller units to be used, especially with appliances.

Abstract: A rotary encoded switch having a plurality of stationary discrete micro switches operated by a rotor having a plurality of concentric cam tracks. The cam tracks and switches are disposed such that for each rotary position of the rotor at least two switches, on opposite sides of the rotor are actuated and a discrete combination of switches is actuated for each position of the rotor. The number of microswitches required is less than half the number of rotary positions.

Abstract: An electronic control system for gaseous fuel burners, particularly suitable for ovens and employs a single push-to-turn user control knob for selecting BAKE, BROIL or SELF-CLEAN modes of operation and for setting the oven temperature desired in the BAKE mode, the control knob turns a potentiometer shaft which provides a signal indicative of the shaft position to a microprocessor which controls relays for selectively opening and closing electrically operated BAKE and BROIL burner valves.
