A timed buzzer assembly having a rectangular base with four terminals insert molded in the base and a generally cup-shaped cover member over the base providing the housing. All of the terminals project through the base member with the armature of the buzzer supported on one terminal and the coil assembly of the buzzer supported on a second terminal. For the purpose of timing the buzzer and also controlling a warning light, a bimetal timer is provided having bimetal elements one supported on a third terminal and the other supported on the above referred to second terminal. The fourth terminal is a ground to which a heating element for the bimetal timer is connected.

Timed buzzer

A warning buzzer having an armature arranged to strike the wall of the cavity formed by the buzzer housing to increase the sound emitted thereby. The buzzer includes terminals molded in a base with one terminal having a coil core and magnetic return leg formed thereon with the coil bobbin received on the core having a pair of lugs on which the coil terminals are wrapped and dip soldered. The dip soldered lugs are then staked in the terminal and in a contact member for both supporting the coil and extending electrical connections thereto.
