What is a One Channel Relay?

A One Channel Relay is an electronic switch that is used to control the operation of a single electrical circuit. It consists of a coil and a switch (usually a mechanical or solid-state switch). When the coil is energized, it activates the switch, allowing current to flow through the controlled circuit. One Channel Relays are commonly used in home automation, industrial control systems, and electronic projects to control high-power devices such as lights, motors, or appliances.
