Abstract
A garage door position indicating system includes a tilt switch attached to a garage door, an RF transmitter coupled to the tilt switch, an RF receiver, and an indicator controlled by the RF receiver. The tilt switch supplies an enable signal to the RF transmitter at selected first tilt positions and blocks the enable signal at selected second tilt positions. The RF transmitter generates an RF signal in response to the enable signal. The RF receiver is responsive to the RF signal and controls an indicator to indicate the position of the garage door.
