A push plate assembly sends a signal to a receiver. The push plate includes a housing, a push plate, a signal generator, a biasing member, a first latch element, a second latch element, and a button. The push plate is movably mounted to the housing. The signal generator includes a switch. The switch is in electrical communication with circuitry through which a signal is transmitted. The biasing member is disposed between the push plate and the signal generator. The biasing member biases the push plate away from the signal generator. The first latch element is connected to the push plate. The second latch element is disposed in the housing. The first latch element and the second latch element engage with one another to limit the movement of the push plate away from the signal generator as the biasing member acts on the push plate.
