Abstract
A hand-held transmitter for the wireless transmitting of signals for operating remote-controlled garage door installations or the like is disclosed. The transmitter comprises a signal generating device, an energy source, and a hand-operable transmitter switch built into the transmitter housing. The transmitter is capable of selectively transmitting at least two different signals and includes a switch which is position-dependent with respect to the force of gravity for selecting one of said at least two different signals to be transmitted.
