Abstract: A switch assembly having a frame bracket with screw holes designed to permit easy and convenient attachment to the frame of a latch gate. The bracket is designed to support a switch arm, a portion of which engages the latch bar mounted on the door or gate of the latch gate. The switch arm includes a contact which is in electrical communication with a switch pole whenever the latch gate is not fully closed and secured. However, when the latch is fully secured, the switch assembly of the present invention is designed to permit the latch bar to engage the switch arm to interrupt electrical communication between the switch arm contact and the switch pole. Thus, the present invention is designed to provide a normally closed switch whenever a latch gate is not fully secured in its locked position for energizing an alarm circuit and to de-energize such an alarm circuit only when the latch gate is in its fully secured and locked position.

Abstract: A manually operated latch for a gate closure is disclosed herein having a resilient helical coil with extended end portions secured to the ends of a pair of hand grips.
