Abstract
A faceplate remote control device is attached to a wall-mounted mechanical light switch that has a toggle actuator. The faceplate remote control device includes a toggle indicator that detects operation of the toggle actuator of the mechanical switch. The toggle indicator causes the generation of an indication of detected operation of the toggle actuator. The toggle indicator comprises a sliding member that is configured to move with the toggle actuator. The toggle indicator may comprise an obstruction detection device that includes an infrared (IR) transmitter and an IR receiver. The faceplate remote control device includes a control circuit and a wireless communication circuit. The control circuit is configured to cause the wireless communication circuit to transmit one or more messages in response to detecting operation of the toggle actuator of the mechanical switch.
