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.

The DMSD is a low-profile DIP switch featuring the industry-standard 2.54 mm pitch and gullwing SMD terminals for reflow soldering. It is designed for address selection, communication protocol configuration and functional parameter settings in industrial and electronic applications.
The product is available with 1 to 10 and 12 positions and uses SPST contacts. With a height of 3.6 mm, it supports space-efficient PCB layouts. Mechanical life is specified at 2,000 switching cycles with an operating force of ≤ 8 N. The operating temperature range extends from -40 °C to +85 °C. Initial contact resistance is ≤ 100 mΩ and remains ≤ 200 mΩ after the specified reliability tests.
Typical applications include industrial automation, building controls, servers, medical devices, robotics and consumer appliances. Common use cases are address configuration, RS485 and Modbus settings, BIOS/CMOS configuration and functional parameter selection. The standardized form factor and footprint enable straightforward integration into existing hardware designs.
