Power relays are types of electric switches that open or close power circuits. A power relay acts as a lever that turns larger currents on or off and detects and prevents overloads or other faults from happening. Power relaying devices commonly work with sound amplifiers, automotive electronics, and telephone systems. Our selection includes different brands, input voltages, and mounting styles. We also have solid-state relays that run similarly to contact relays without the moving parts, and time-delay relays that open or close on delayed timeframes. Additionally, we carry relay accessories such as mounting bases and hardware kits.
