Electrical Relays
Relays are a type of switching device that controls the flow of electric current by opening or closing circuits to enable different functions including remote control, automation and protection.
Our range of electrical relays are sourced from industry-leading brands such as Hager, SCL and LS Industrial Systems for reliable and high-quality performance.

Why are relays important?
Electrical relays are essential components found in industrial, home and consumer electrical systems. They contain switch contacts with the ability to switch power effectively within a control circuit, allowing for the precise operation of electric motors and providing protection against voltage spikes. They can isolate faulty circuits, detect overloads and short circuits to prevent damage to the equipment and reducing the risk of injury. Relays are reliable and long-lasting and can help to optimise energy usage and improve overall system performance.
What is the lifespan of an electrical relay?
Most electrical relays will last several years, although this is dependent on several factors. Operating conditions and switching frequency can reduce lifespan overall, however good maintenance will help relays last longer.
What are some common uses for electrical relays?
Electrical relays are used in thousands of household and industrial electrical items across many types of motor, lighting, heating, cars, security and medical devices. For example, relays are used to start, stop and reverse the direction of motors, benefiting the operation of machinery and process control, while relays can also perform actions such as regulating temperature in heating systems, activate security lighting or control windscreen wipers depending on the signal received.
