Relays

What is a Relay?

Relays are electrically operated switches that open and close circuits receiving electrical signals from external sources. The relays built into electrical products work in a similar way; they receive an electrical signal and send the signal to other equipment by turning the switch on and off. The three main functions of relays are to allow a small amount of electrical current to control high current loads, send different types of electrical signals, and drive multiple outputs with just one input.

What really sets us aside from our competition is our choice and range of relays – you really don’t need to look anywhere else for your requirements.

As we have been operating for over forty years, we have developed a fantastic relationship with our suppliers. This benefits us in two main ways: We gain access to the widest choice of components from those suppliers, and secondly, they sell us those components at competitive prices because we purchase such significant volumes. We are able to pass on those competitive prices to you, our customer.

We have a large stockholding of our products at our warehouse in Dukinfield, Cheshire in the UK. This stock means that our product availability is consistently high, and we can get your order for stock items out to you in a 24 to 48 hour time frame.
