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.


MSM II-Switch with common anode control of the RGB LED
The well-established MSM II mechanical switch family is growing. With the MSM II (Common Anode), Schurter is introducing a variant that uses a common anode to control the RGB LED illumination. This combines the familiar robust mechanics with visualization technology for clear feedback, easy integration, and maximum reliability in control and operating solutions.
RGB LEDs can be controlled either via a common anode (+) or a common cathode (–). While with common cathode all negative poles are connected together and the colors are controlled individually via the positive pole, the common anode variant does the opposite: all positive poles are connected, and the color channels are switched separately to ground.
The MSM II (common anode) offers maximum compatibility with modern driver ICs, PLC outputs, and microcontrollers, which are predominantly designed for common anode control. This facilitates integration thanks to a simple signal structure and reduced wiring requirements.
The combination of tactile precision, IP67 protection, robust design, and flexible RGB signaling makes the MSM II switch ideal for a wide range of applications, particularly in industrial control units such as control panels, production facilities, building automation, and access solutions.
