Abstract
A device incorporated in a push button switch for representing the status of the switch has a representing plate member having an arm which is rotatably held at its mid portion by a supporting member. The arrangement is such that the sum of the stroke of an operation rod and a rotation of the arm is transmitted to the representing plate member to provide a larger stroke of the later, so as to ensure a distinctive representation for a given stroke of the push button.
