ABSTRACT:
A single pole, single throw switch for flashlights and other low amperage circuits is enclosed in a dielectric housing having an electric circuit contact fixed therein, the switch being selectively actuable by moving a threaded portion of a first electrode into and out of a complementarily threaded portion of a second electrode. Relative motion of the electrodes is achieved by manually rotating a cap-like part of the housing to which the first electrode is fixed. Voltages that can be accommodated by the switch are limited by the associated I.sup.2 R effects of contact resistance during switch actuation. Various components of the switch are fixed in the dielectric housing by friction, tongue and groove fasteners, and screws to facilitate servicing and repair.
