ABSTRACT:
A push button switch, particularly a master switch, has housing-affixed contacts (4, 7) and at least one contact bridge (8, 9) movable by a spring plunger (10). A spring-switching mechanism (24, 25, 26) is operatively coupled between the spring plunger and a manually-movable sliding switch, or switch actuator, (22). A guiding, or sliding, locking linkage apparatus for the sliding switch (22), which includes two locking parts, a first of which is a track (27) and a second of which is a follower lever (28) for engaging the track. Upon alternate depressions of the sliding switch, the sliding switch alternately moves between "on" and "off" positions. In order to prevent damage to the locking apparatus upon a pulling of the sliding switch in a direction opposite to a direction of depression of the sliding switch, the first and second locking parts release from the housing to follow movement of the sliding switch.
