Rotary limit switches detect and are activated by rotational movement. Switches are devices used to break electrical circuits. Limit switches are essentially switches that can be actuated by an object ...

Solid state limit switches contain no moving parts. They detect objects using an optical sensor or other electronic device, and switch using solid state components such as resistors, capacitors, and ...

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.
