ABSTRACT:
A multi-pole switch includes a wobble stick type actuator provided with a contactor engaging the free end portions of a plurality of displaceable resilient inner pin contacts having their base portions fixedly mounted in a support member. A plurality of stationary pin contacts are disposed radially outside and adjacent said displaceable pin contacts. A guide member adjacent the contactor includes a plurality of radially extending slots therethrough each housing a portion of one of the displaceable pin contacts and one of the stationary pin contacts in a normally spaced apart manner. A biasing element normally maintains the contactor in a central, neutral position whereby, upon deflection of the actuator the contactor is radially displaced and correspondingly displaces a selected inner pin contact into engagement with its radially adjacent stationary pin contact in the same guide member slot to close a circuit between the engaging contacts.
