Abstract
A plunger-operated magnetically actuated switch enclosed in a generally cylindrical housing which may be mounted either within a cylindrical cavity or against a flat surface. A magnetic contact reed switch is housed alongside the guide for a plunger which carries a small permanent magnet. Depressing the plunger moves the magnet sufficiently to operate the magnetic reed switch. Optional plunger length and reed switch location provide for setting the switch in either a normally open or normally closed configuration. A flange is provided for securely mounting the switch unit in a cylindrical cavity. A resilient catch and a pair of mating hooks are provided to attach a flat mounting plate to the side of the housing and permit the switch unit to be mounted against a flat surface.
