Abstract

The hand held transmitter transmits two different radio signals to open a garage door or similar from a distance. The transmitter has a gravity switch that operates depending on the transmitter's orientation in the earth's gravitational field. The gravity switch is a mercury switch and has three or more contacts. It is fixed directly to the inside of the housing. An LED mounted on the housing indicates when the transmitter's battery voltage is unacceptably low. The advantage lies in using only one switch to send two different signals.
