UHF Remote (radio) Controlled Relays Kit
(PC board only shown to left; kit contains all component parts.)
Two separate relays can be switched via encoded signals transmitted from a keychain size, two-button transmitter (like those used for car alarms and electric car doors). Push a button and relay toggles "closed" and one more push toggles it "open". Transmit distance is about 120 feet maximum. The receiver requires from 12 to 15 volts DC. The transmitter is supplied assembled and tested complete with its own battery. Tricky (receiver) parts of the circuit are supplied already-assembled and tested; just plug them in and solder in place. Each relay can handle up to 10 amps @ 120V AC; plenty for numerous applications; control lights, door locks, magic shows etc.
