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 Do We Supply?

We have a broad range of relays in stock, including:
Modular step relays
Monostable relays
Ultra-slim PCB relays
Relay interface modules
Miniature PCB/plug-in relays
Low profile PCB relays
Miniature industrial relays
Safety relays
Power relays

Why Choose E. Preston?

We are an official distributor and wholesaler of relays from brands such as Crouzet, Crydom and Finder. These are well known companies in their fields with excellent reputations for the quality of their products.

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.
and we can talk through your specific relay requirements.

distribution systems.

Appliance Outlet 4763 IEC Type F / J

  • Combines 10 A and 16 A in a single component
  • High design flexibility for PDUs
  • Compatible with dimensions of existing Type J
    outlets, e.g. 4797-5

With the new 4763 Type F/J outlet, Schurter offers a flexible solution for modern power distribution systems, particularly in data centers. By combining Type F and Type J in a single outlet, the 4763 supports different current ratings while simplifying the design of intelligent PDUs.

A key advantage is its full mechanical compatibility with existing Type J outlets such as the Schurter
4797-5. Identical cut-out dimensions allow existing designs to be reused without modifications to front
panels or PCB layouts, reducing development effort and simplifying retrofits.

For maximum design flexibility, the outlet is available with optional light guides for status indication and
various configurations to accommodate different panel thicknesses. It supports PCB mounting, operates
reliably from –25 °C to +70 °C, and complies with relevant TÜV requirements.

Additionally, the 4763 supports established cord retention systems such as V-Lock, P-Lock, and TwyLock,
ensuring secure connections in critical applications.

This makes the new Schurter 4763 an ideal choice for data center, industrial, IT and
telecommunications applications where flexibility, reliability and easy integration are essential.
