  • Vermin trap signaling device
    Patent number: 8933812
    Abstract: A signaling device that indicates actuation of a remotely located mousetrap comprises a base that supports the trap, a power supply, and a mounted electrical interface switch. The switch is held open by a non-conductive interrupter positioned between the switch contacts and connected to the bail of the trap. The bail dislodges the interrupter and closes its switch when the trap is actuated, producing a visual flashing light at the users location. The signaling device can be tested by a test actuator switch located at the users location. A tether clips the signaling device to the trap.
