ABSTRACT:
A push-button switch includes a fixed member having a first fixed contact strip disposed on the inner surface of the fixed member and a second fixed contact strip disposed on the inner surface of the fixed member and opposite the first fixed contact strip; a control member biased by a spring from the fixed member and locked in a desired position; and a movable contact strip configured, when attached to the control member locked in the desired position, to be in contact with and to short-circuit the first fixed contact strip and the second fixed contact strip. The movable contact strip is configured to be isolated from the first and second fixed contact strips at substantially the same time when the control member is controlled against a biasing force of the spring.
