With over 40 years in magnetic switch manufacturing and a large flexible range of magnetic sensors, Thomas White Ltd. are perfectly placed to satisfy your magnetic switch requirements. Design and manufacturing is in house so we react quickly to provide a high quality service and an excellent product.

At Thomas White, we solve your everyday problems of industrial switching using non-contact magnetic sensors. We take your brief, develop a magnetic switch or reed switch to do the job, then manufacture it in quantities from 10 to 10,000.

Our customers work in robotics and automation, in industrial processes from automobiles to food processing, in medicine and marine industries. They choose us because our magnetic switch & reed switch expertise applies to any engineering application, including pneumatic cylinders, liquid flows and levels, door and window security, and counting systems.

No magnetic switching challenge too tough

Our skills bridge the gap between electrical and mechanical engineering. We blend electronics and engineering to help you stay in control of everyday production processes, heavy engineering, inhospitable environments, and medical equipment.

Free prototype development

If the brief justifies it, we're happy to produce a prototype magnetic switch or reed switch for free. We’ll work with you to get to the heart of your engineering challenges.

Bespoke switches or ready-made sensors

As well as bespoke magnetic switches, we produce a range of ready-made magnetic proximity sensors using reed switches and solid-state Hall-effect or GMR technologies.

Brand your own magnetic & reed switches / sensors

We'll put your badge on any bespoke or ready-made magnetic switch or reed switch.
