Abstract
A remote control transmitter utilizing single-pole, single-throw switches for connecting frequency determining capacitors and a battery in circuit with an LC oscillator is shown. The switches can be push-button type switches which close a pair of contacts. The battery is connected in circuit with the oscillator by a semiconductor switch which is closed by closure of any one of the push-button switches. Diodes isolate the frequency determining capacitors from each other.
