Collection: Relays
A relay is a device which is used to turn on and off a heavier load from a smaller signal. They are traditionally an electro-mechanical device, although solid state semiconductor relays are also popular. One of the key characteristics of relays is that there is a physical seperation between the activating signal and the load power. For example a small battery can energize a relay to turn on a large wall-powered AC load such as an electric motor.
We stock a large variety of both electro-mechanical relays and solid state relays. For contactors and and starters specifically designed for starting electric motors, please see our Motor Contactors and Starters collection.
