Abstract
A switch including an elongated tubular base member having a plurality of ring shaped insulators and conductors alternately mounted thereon and having threads formed in the outer surface thereof. A switching control ring having mating threads in the inner surface thereof and a conducting surface in sliding engagement with the outer surface of the ring shaped insulators and conductors so that switching action occurs as the control ring is moved axially along the structure. The elongated tubular base member operates as a housing to receive electronic circuitry therein, which circuitry may be sealed so that the assembled apparatus provides external switching for the internal circuitry of a hermetically sealed unit.
