发明名称 Telephone hookswitch actuator and handset support assembly
摘要 A telephone hookswitch actuator and handset support assembly arranged to allow a telephone instrument to be used as either a desk or wall unit. The actuator is constructed of two independently pivoting members, a first hookswitch actuator member controlling the "on-hook" and "off-hook" switching and a second alternatively positionable support member. When the telephone instrument is intended to be used as a desk unit a retaining device manipulated from the exterior of the telephone is adjusted out of contact with the support member allowing the support member and actuator to act in unison. When used as a wall unit the retaining device is adjusted into contact with the support member which then retains the member outwardly extended allowing a cavity on the handset to accept the support member, supporting the handset.
