Abstract

See full text

A telephone instrument has a rectangular recess (3) along one side of the body which receives the handset. The handset has a recess which fits over a locating member (2) when on-hook. The hook switch contacts (6) are controlled by a pivoted member (4), which acts on the end of a plunger (7) to control the hook-switch contacts. The plunger (7) is spring-urged to its off-hook condition, i.e. when the handset is not in the recess.
