This UHF remote switch uses a secure rolling code system. The receiver uses all through-hole parts, fits in a compact plastic case and can be powered from 12V or 24V DC. Up to 16 transmitters can be used per receiver; they fit into handy keyfob cases, and you can use a prebuilt transmitter module or discrete components. by John Clarke
