ABSTRACT:
A push-button switch operates by depression of a push-button to move a movable contact into engagement with respective fixed contacts. The push-button when depressed rotates a roller through a predetermined angle by means of interengaging ratchet-type teeth on the push-button and roller respectively. A two-arm lever engages an indented outer surface of the roller, so that forward or reverse pivotal movements of the lever are effected whenever the push-button is depressed. The lever operates the movable contact. The roller also carries a segmented colored disc so that alternating colors are associated with the push-button to represent the respective movable contact positions.
