Abstract
Abstract A solid state switch is provided which embodies a push button mode of operation and which is capable of a variety of different types of uses. This switch includes a housing having a hollow interior and an open end wall formed at one end thereof communicating therewith, a push button supported at the other end of the housing for movement relative thereto, and a base configured so as to be mountable within the open end wall of the housing. A plurality of leads are mounted on the base so as to project outwardly therefrom on one side thereof while an upstanding slide guide is affixed to the other side of the base. A solid state switching element is suitably supported on the slide guide. The other components of the switch are supported by the base so as to be positioned within the hollow interior of the housing. In this connection, the switch further includes a retaining button which is operatively connected at one end to the push button so as to be movable therewith, and has the other end thereof positioned in engagement with a spring biased magnet carrier. The latter carrier has a hollow interior and supports a pair of magnets therewithin. In response to actuation of the push button, the magnet carrier is movable between a first position wherein the pair of magnets bear a first relationship to the solid state switching element thereby to establish a first operating condition of the switch, and a second position wherein the pair of magnets bear a second relationship to the solid state switching element thereby to establish a second operating condition of the switch.
