ABSTRACT:
A push button switch is provided to include a key cap, a baseplate, a switch element, an internal arm element, an external arm element and an elastic element. The switch element is disposed on the baseplate and made selectively electrically conductive in response to up-and-down motion of the key cap. The internal arm element is movably connected to the baseplate and has a receiving space. The elastic member is disposed within the receiving space and moves responsive to movement of the key cap and selectively actuates the switch element. The improvement of the push button switch is characterized in that the internal arm element, which is movably connected to the baseplate, has a receiving space for accommodating the elastic member. The elastic member moves responsive to movement of the key cap and selectively actuates the switch element.
