Patent ID: 7579565

Claim:
A mechanical timer switch assembly for replacing an electric toggle switch comprising: a replacement cover plate having an inner and an outer side sized to fit over an electric receptacle box as a replacement for a conventional toggle switch cover plate; a mechanical spring actuated rotary timer switch including a spring, a rotatable shaft and a contact member moveable by said shaft to open and close an electrical circuit, and said timer switch sized to fit into the electrical receptacle box and fixed to said inner side of said replacement cover plate with said shaft extending through said cover plate; a knob fixed to said shaft outside of said replacement cover plate for rotating said shaft to close an electrical circuit and actuate said spring actuated rotary timer switch to open the circuit after a predetermined time; a second mechanical switch fixed to said inner side of said replacement cover having an actuating member extending through said replacement cover for opening and closing the electrical circuit; and electrical circuit means connecting said mechanical spring actuated rotary timer switch, said second mechanical on/off switch to an electric light and a source of electrical energy so that the electric light can be switched on or off by either switch and wherein said electrical circuit means is a three way switch circuit and each of said switches is separately wired to turn a second light on and off independent of the other switch and which includes an inner housing with said mechanical spring actuated rotary timer switch disposed therein and said second mechanical switch is a push button switch and wherein said mechanical timer switch assembly includes a flat rectangular actuator plate for opening and closing an electrical circuit.
