Abstract
A push button switch, particularly a power supply switch, has contacts (4, 5) attached to a housing and a movable contact bridge (8) which is moved by means of a spring plunger (10'). A spring switching mechanism (26) transmits force between the spring plunger (10') and a manually-actuated switch actuator (22'). The switch actuator (22') is alternately latched and unlatched by a locking linkage (27, 28) which alternately holds the switch actuator in 'switched-on' and 'switched-off' positions when the switch actuator is repeatedly pushed. Additionally, a switching rocker (51) is provided between the switch actuator (22') and the spring plunger (10') to improve switching action. The switching rocker (51), at the beginning of 'switching-on' and 'switching-off' operations, forcibly carries the spring plunger (10') in its respective switching direction through a partial path of its contact stroke (H). Following this partial path the spring switching mechanism (26) moves the spring plunger (10') to its respective 'switched-on' or 'switched-off' position.
