Abstract

A push button switch, which comprises a shell with guide box, a key top with base seat, and a return spring installed between the shell and the key top in which the base seat moves along the guide box to undergo contact change, which is characterized in that the key rods are separately slidably installed toward the guide box and the base seat between the guide box and the base seat, the return spring is installed between the key top and the key rod, a second spring with push-down section installed in series with the return spring between the key rods which reversibly reduces the effective length of movement direction of the base seat when the key rod is pushed, meanwhile uses the reverse force to undergo part of the contact change.
