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.
