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 ...

A flap controller needs current limiting to protect the motor when the flap reaches full closure. A small incandescent lamp can perform this task without the need for more costly limit switches or a ...

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.

There are a bunch of low cost cnc engraving machines loosely called ‘3018’ as they cut material up to 30 x 18cm, and the same parts are used in two smaller sizes down to a 1610. They are not the ...
