Mechanical position and electrical circuitry meet in the no-nonsense limit switch. These cost-effective input devices excel in tough environments and are as simple to install as they are to maintain.

You use limit switches to switch off a motor if it reaches one of its two end positions. Even if you build a microprocessor-based motor controller, you should switch off a motor with hardware by ...

We’re used to thinking of limit switches as a mechanical device that cuts the motor connection before physical damage can occur. [Anthony] decided to try a different route with this project. He built ...
