Patent ID: 7291796

Claim:
A press switch having a force-to-detach function, comprising: a base, being a hollow base and having an open top, and including at least one chamber for accommodating and fixing input and output terminals of an electrode device, and each terminal of the input and output terminals includes a fixed contact point and a pair of electric conducting pillars being disposed therebetween; a contractible pulling rod, having a press rod at a top, an actuator transversally extended from a middle section of the contractible pulling rod and coupled with at least one press terminal, and a movable contact point being separately disposed on each of two opposing ends of the at least one press terminal and corresponding to one of two fixed contact points of the input and output terminals, and said contractible pulling rod and the at least one press terminal being coupled to a pair of electric conducting pillars for being lifted; an upper casing, for covering and sealing said base, and having a press rod being extended from a top and a support axle section being disposed at an end; and an actuator, having an end axially coupled to said support axle section and an internal wall coupled to said press rod, and a resilient spring being disposed between said upper casing and said actuator; such that if said actuator is pressed to compress said resilient spring, said contractible pulling rod and the at least one press terminal move downward until each movable contact point is in contact with said fixed contact points of said input and output terminals on opposing sides of the base to electrically connect to a power supply; if said actuator is released, an extension of said resilient spring lifts and contractible pulling rod and a press terminal thereof, so as to force two movable contact points to be detached from said two fixed contact points of said input and output terminals, so as to disconnect from the power supply.
