Abstract
An alternate action headlamp switch with mechanical logic is provided. One plunger and overcentering latching mechanism are provided for a push-push operation to turn parking lights on and off. A second plunger and like latching mechanism are provided for turning headlamps on and off. Interlocking mechanism between the plungers is provided so that when the headlamp plunger is depressed the park plunger is also depressed whereby to turn on both the headlamps and the parking lights. Further interconnecting mechanism is provided so that if the park plunger is already depressed and the parking lights are on, depression of the headlamp plunger will release the park plunger latching mechanism. The operating portion of the parking light plunger is held in on condition through the interconnection with the headlamp plunger until such time as the headlamp plunger is again depressed to release it whereby the headlamps and parking lights simultaneously are extinguished.
