ABSTRACT:
A toggle switch housed in a body and including a generally rectangular conductive blade pivotally mounted on a central conductive terminal post provided with fulcrum support means including one or two fulcrum supports, the blade being capable of assuming two or three operative positions relative to a pair of conductive terminal posts flanking the central post, depending upon pivotal swinging of the blade about the fulcrum support means, which contacts the blade centrally of its width. A dielectric actuator tip, pivotally mounted centrally in the body, is resiliently biased toward the blade and includes a bifurcated portion terminating in a pair of spaced toes slidably contacting the blade along parallel paths spaced on opposite sides of the fulcrum support means.
