Abstract: A gas flow control and igniter switch assembly for a gas appliance includes a valve body having a stem, an igniter activating switch and a knob, wherein the igniter is activated upon depressing of the knob a predetermined distance. The igniter switch is preferably constituted by a multi-piece outer casing within which is mounted multiple igniter contacts, an electrical connector, and an activating member. The activating member carries the electrical connector and is biased to a position which maintains an electric circuit to the igniter open. The multi-piece outer casing is adapted to be snap-fittingly secured together and mounted about the stem of the valve. Preferably, the stem extends freely through the outer casing but press-fittingly receives the activating member such that the activating member moves in axial unison with the stem.

Abstract: A switch assembly usable in a food waste disposer is disclosed having several improvements over the prior art. The switch assembly positively retains an overload switch, making assembly of the switch into the disposer easier. The switch assembly includes terminals, which attach to the start and run windings of the disposer. The terminals are arranged in a uniform direction along a single side of the switch assembly. This arrangement allows a single, integrated connector of winding leads to be easily connected to the switch assembly, facilitating assembly and reducing the possibility of incorrectly wiring the disposer during construction.
