ABSTRACT:
A rotary ignition switch has a pair of tiltable bridges extending in opposed directions and spring-pressed toward a center contact. When the switch is rotated a first end of one bridge remains against the center contact while its other or contact end rides up a helical cam track. The first end of the other bridge rests on the one bridge while its other or contact end also rides up a helical track. The contact ends of both bridges then drop off the helical cam tracks onto fixed contacts to complete respective circuits.
