A push button electric switch including a pair of fixedly mounted spaced contacts and an actuator for moving a conductive ball into and out of bridging engagement with the contacts. The actuator is coupled to a toggle mechanism which produces an increasing reaction force as the actuator is depressed until the force abruptly diminishes, providing a "snap" feel, when the actuator reaches a position corresponding to the bridging of the contacts.
