E. Preston (Electrical) Ltd 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 do 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 consumer.
The company, which is still wholly owned by the Directors, is located on a modern industrial estate which lies six miles to the east of Manchester in the North West of England.

Schurter EDC Electro-Mechanical Direct Current Switch
Schurter launched an electromechanical micro switch with a switching capacity of 10A,48VDC.
EDC: Safe Switching of Direct Current
Uniquely compact design – ideal for mobile applications
Extremely durable (over 1 million switching cycles)
Available in 2 versions (universal and Schurter specific)
Rated current 10 A at 48 VDC
The Schurter EDC (Electronic Direct Current) switch was specifically engineered for the reliable switching of direct current in compact systems. It combines the mechanical precision of a microswitch with integrated power electronics.
The result of Schurter's new development: completely arc-free. Arcing is one of the greatest safety risks when switching direct current. The use of modern semiconductors completely eliminates arcing.
With the well-known feel of mechanical switches, the load current is switched electronically without galvanic isolation. This protects both the system and the environment from damage caused by sparking or EMC interference.
Long-Lasting and Reliable At the same time, the EDC achieves well over a million switching cycles, as there is no arc-related erosion of the contacts. This extends the service life and reduces maintenance costs.
Ultra-Compact Design Thanks to its compact design, the switch can also be integrated in confined installation situations. This is ideal for onboard systems in electromobility, compact power distribution systems in the aerospace industry or mobile robot solutions. The EDC also scores highly in industrial control systems with battery buffered DC supply thanks to its high level of safety, energy efficiency and ease of installation.
2 Variants The new Schurter EDC is available in two versions. Firstly, as a stand-alone version (EDC 02) for universal actuators, and secondly as a Schurter-specific version for the MSM II switch as an actuator (EDC 01). Both versions are designed for a rated current of 10 A at 48 VDC.
Robust and Future-Proof With the EDC switch, Schurter addresses the growing demands for safety, miniaturization and eliability in modern DC applications – a robust solution for future-proof designs.
Reliable supply chains, expert support, and long-term product availability have never been more important. Schurter provides not only high-quality EMC Filters – but also the tools and service to back them up.
