Hookswitch mechanism for telephone handset
First Claim
1. A hookswitch mechanism adapted to be mounted on a telephone instrument for operation thereof by the cradle for receiving a handset of said telephone instrument, said mechanism including a plunger translatable axially within an enclosing housing in response to pivotal movement of a base section of said cradle, said housing bearing a plurality of contact closure members substantially normal to the axis of said plunger, means responsive to axial movement of said plunger for opening and closing circuit paths including said contact closure members, and wherein said plunger comprises a head adapted to be engaged by said cradle and a tubular body secured to said head for axial movement therewith.

Abstract
A hookswitch mechanism adapted to be operated responsive to movement of the cradle of a telephone instrument. The hookswitch mechanism has a plunger, axially operable to open and close contacts. The movable contacts are rectangular strips mounted on the movable plunger body. A housing encloses the plunger body and mounts the stationary contacts adjacent the ends of the contact strips. The mechanism is mounted on a bracket which also supports the cradle for pivotal movement thereby ensuring the relative positioning and alignment of cradle and hookswitch mechanism.
