Radio-controlled or remote-controlled toys, commonly referred to as RC toys,rc switch ， are self-powered and can be controlled from a distance using a remote control that works with radio waves.
When we press the control, the transmitter sends a specific number of electrical pulses through the air, corresponding to that action. The transmitter has its own power source, usually in the form of a 9-volt battery. Without a battery, the transmitter cannot send radio waves to the receiver.
Once the RC toy receives the radio waves, the motors are activated to produce a specific action. The power supply powers all working parts including the motor. The transmitter is controlled by radio waves, and the receiver activates the motor. When we press a button on the transmitter to advance or rewind the RC toy, a pair of electrical contacts make contact. The receiver recognizes the signal and sends it to the circuit.
