Over 40 years of Excellence
E Preston has been a specialist distributor of electrical and electronic components since 1980, offering thousands of products to meet a wide variety of needs and applications.
But we do more than simply sell components – we have built a reputation as a company who does business the traditional and honest way. Paying attention to the simple things – like phoning people back when we say we will – has kept our customers coming back for over four decades.
Our staff are experts in their fields, we maintain appropriate stock levels, and all of our processes are fully computerised to ensure a smooth operation.
We also understand that business is carried out between people, not companies. We do the hard work to maintain relationships with our suppliers as well as our customers. That way everybody in every part of the supply chain is satisfied – from the manufacturer to the end customer.

The solid state relay portfolio is used in all applications where mechanical relays reach their limits. They switch more frequently, quieter and faster than mechanical relays and are particularly suitable for applications in buses and trucks, in agricultural vehicles and construction machinery, in specialty vehicles and passenger cars.
E-T-A solid state relays are available for DC 12 V and DC 24 V applications and are suitable for standard automotive relay sockets to ISO 7588.
Solid state relays combine high-end power semi-conductors with comprehensive know-how in the areas of heat management, EMC-compliant design and overcurrent protection. The electronic circuitry ensures wear-free, silent and extremely fast switching operations over the entire life span.

The electronic standard relays type ESR10 Micro are solid state relays for DC 12 V and DC 24 V vehicle applications. This space-saving relay is available in three power classes:
Their Benefits Include:
The ESR10 Micro relays can easily replace an electro-mechanical relay because polarity of the control input does not matter. The solid state relays are suitable for switching resistive, inductive and capacitive or lamp loads. Unlike electro-mechanical relays they offer frequency control as an option.

The connector system for quick, easy, and safe bus cabling and signal applications. It meets all the requirements of modern building installation.

Low-Voltage Technology
These connectors are used to distribute signals in buildings, in parallel to the distribution of power. Mechanical coding and clear assignment with different colors facilitate assembly. Complex installations can be realized with just four basic components – from the sub-distribution unit to any point of use. The connectors come as male and female connectors complete with strain relief and can be used to connect any current type of cable.
The BST14 are designed according to the KNX manual.
The 5G2.5/4+2X1.5 flat cable with shielded bus, as per the KNX manual, is available for the combined distribution of energy and signals.
Best Choice Value Program
