Transmitter cut-off device

In a transmitter cut-off device for use in a conventional hand-held telephone transmitter-receiver unit, said unit including a main body;

• a transmitter housing having a lip, said housing being disposed in a recess in said body;
• a pair of spring contacts disposed in said housing;
• a transmitter cap having a downwardly extending side wall, said cap being removably secured to said main body;
• and a transmitter having an upper surface in confronting relation with said cap and a bottom surface opposite said upper surface, said transmitter being disposed in the cavity defined between said transmitter housing and said cap, the periphery of said lower surface being seated on said lip, said transmitter having a pair of transmitter contacts disposed on the bottom surface thereof, each of said transmitter contacts being seated in electrical conducting relation with its corresponding spring contact, said transmitter cut-off device being of the type wherein transmitter cut-off is effectuated by unseating at least one of said transmitter contacts from its corresponding spring contact, the improvement comprising said cap having a vertically extending guideway disposed in said side wall, the interior of said side wall opposite said guideway having a support surface, said support surface being in close confronting relation with the upper surface of said transmitter, a manually operable actuator extending through said guideway and being secured directly to the body of said transmitter for effectuating movement of said transmitter, said actuator being movable between a first position in which each of said transmitter contacts is held in electrical conducting relation with its corresponding spring contact by the combination of said actuator and said support surface, and a second position in which at least one of said transmitter contacts is unseated from its corresponding spring contact, said lip serving as a fulcrum upon which the body of said transmitter is pivoted, and means for releasably securing said actuator in either of said first and second positions.
