Non-contact magnetic switches and sensors developed and manufactured for a wide range of industrial, marine, and automation applications

At Thomas White, we solve your everyday problems of industrial switching using non-contact magnetic sensors. We take your brief, develop a magnetic 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 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 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 switches and sensors

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