Relay switches (also called an electrical relay or an electrical relay switch) use a small amount of power to control a larger source of power connected to electrical devices such as car motors, computers, and lighting installations. A basic relay switch has a control circuit with an electromagnetic coil and a load circuit with contacts and a lever. When current flows into the relay switch, it moves through the coil and a magnetic field is created, which causes the lever in the load circuit to move between contacts, either turning the device on or off. In a normally open (NO) relay switch, when power is supplied to the relay, the load circuit is closed and the power source connected to the relay is turned on. In a normally closed (NC) relay switch, when power is supplied to the relay, the load circuit is open and the power source connected to the relay is turned off. In other types of relay switches, non-moving parts such as transistors or semiconductors can be used as the control circuit to operate the switching mechanism. Relay switches can be controlled with an external switch, such as a light switch, or they can be connected to an automatically switched power source, such as a car ignition. One relay can operate multiple switches, and multiple relays can be operated with a single switch, with each relay operating independently from the other relays in the system.
Supco manufactures test instruments and replacement parts for heating, ventilation, air conditioning, and refrigeration systems. The company, founded in 1945, is headquartered in Allenwood, NJ.

Matters Needing Attention:
1. The current on the product is the maximum load current, not the rated current.
2. On the basis of the different of the load character,you should keep the different allowance on the level of the current when you choose the product.(When the load is resistive, the load current should be 1/2-1/3 times of the max load current .When the load is inductive or capacitive,like motor， transformer， the load current should be 1/4-1/6 times of max load current.)
3. When Installation,solid state plater and radiator with smeared thermal conductivity silicone grease
