In a programming device for controlling the selective transmission of a signal to selected receivers at preselected times, commutators have their slides moved by remote control to selected commutator bars. A timing device makes connections through the commutator bars, the slide of each commutator making a connection at a different time to each different commutator bar of a given commutator. The connection made by the timing device through a commutator bar energizes a relay, which closes the circuit between the transmitter and the corresponding receiver. Parallel circuits are provided from the circuit to the transmitter to energize the transmitter only when at least one of the receivers is connected to receive. The individual commutators may each be brought to a home position also by remote control. The commutators may be mechanically driven by a motor or may be driven by stepping motors.
A programming system for controlling the selected transmission of a signal at preselected times comprising a transmitter, a plurality of receivers, a plurality of relay means one for each of said receivers for connecting the corresponding receiver to said transmitter when such relay means is energized, a plurality of commutator means one for each of said relay means, each commutator means having a plurality of commutator circuits and being operable to select one of its commutator circuits and provide a connection between said relay means and the selected one of the commutator circuits thereof, and means to provide power to the commutator circuits of said commutator means at different preselected times to energize each of said relay means at a preselected time corresponding to the commutator circuit selected by the corresponding commutator means to thereby connect said transmitter to the corresponding receiver at the preselected time.
