Porch or entry switch providing emergency signals

Claim 1

A switch which may be used such as for controlling a porch light for providing an emergency signal, the switch comprising: a switch body of non-conductive material having an open top cavity therein; a first fixed electrical contact member secured to said switch body within said cavity and having a first means for connecting a first electrical conductor thereto; a second fixed electrical contact member secured to said switch body within said cavity and having second means to connect a second electrical conductor thereon; a third fixed electrical contact member secured to said switch body within said cavity and having third means to connect a conductor thereto; a first elongated leaf spring of electrical conductive material secured at one end thereof to said first fixed electrical contact member and having a contact point at the other end thereof, the contact point engaging said second fixed contact member when the first leaf spring is in its non-deflected position; a second elongated leaf spring of electrical conductive material secured at one end thereof to said second fixed contact member and having at the other end thereof a contact point engaging said third fixed contact member when the second leaf spring is in its non-deflected position; a flasher means secured to said switch body and having two electrical conductors extending therefrom, one of said conductors being connected to said first fixed contact member and the other conductor being connected to said third fixed contact member; a toggle pivotally supported within said switch body having integral actuator post portions extending therefrom, the toggle being supportable in a first "OFF" position wherein said post portions deflect both said leaf springs whereby no continuity is provided through said switch between said first and second electrical contact members, and a second or "ON" position wherein said post portions permit said first leaf spring to return to its non-detected position providing continuity between said first and second fixed electrical contact members, and a third or "FLASHER" position wherein said posts deflect said first leaf spring but permit said second leaf spring to return to its non-deflected position providing continuity between said first and second fixed electrical contact members through said flasher means; a toggle plate affixed to said switch body closing said cavity therein and pivotally receiving said member within said switch body cavity; a position retention bar positioned within said switch body and in contact with said toggle; and spring bias means urging said position retention bar against said toggle and said toggle against said toggle plate to retain said toggle in position when said toggle plate is secured to said switch body.
