Abstract
A rotary indexing switch includes a base having a series of radially spaced stationary contact areas, and a rotary contact member having a rotary contact area. The stationary contact areas are defined by contact members engaged within passages in an insulating ring in a configuration dictated by specifications of the switch. The switch has a number of unique features, including mating engagement structure that drivingly engages actuator shafts of stacked switch assemblies; a spring for biasing the rotary contact member toward the stationary contact areas; a combination lift and detent arrangement for lifting the rotary contact areas away from the stationary contact areas and maintaining the rotary contact member in a contact position when the rotary contact areas are engaged with the stationary contact areas; a center contact selectively engageable with the base utilizing a cooperating engagement arrangement; and an integral enclosure wall which forms a dust shield.
