Abstract
A press-button switch is provided which includes a control unit between a press button and a conductive switching element within a housing of the press-button switch. The control unit utilizes a push element and a hook member beneath the press button to push and pull, respectively, against a first and a second actuating element both of which are situated at different planes. Thus, the rotary body of the control unit can continuously rotate at an angle of 180 degrees in a single direction, and the eccentric hole will change its position between an upper point (H) and a lower point (L) in order to move the push-pull rod for displacing the switching element for the on-off control. Moreover, the press-button switch can be smoothly disconnected in off state for ensuring the electric safety in case of overload current.
