ABSTRACT:
An electric coil is coupled across a pair of normally closed electric contacts which are attached to two electric terminals. The contacts and terminals are supported by pockets in an insulating base member which also supports a bobbin upon which the electric coil is wound. Each terminal is supported within its pocket by a pair of spaced legs having projecting spurs which bite into the margins of the pockets and prevent the terminals from being withdrawn. An armature is pivotally mounted over one end of the coil, and an actuating arm is attached to the armature for opening the contacts in response to a predetermined amount of movement by an object in contact with the actuating arm. This energizes the coil by removing the short circuit around it and causes the armature to buzz until the coil is de-energized.
