Limit switch
Understand the Problem
The question appears to be a general inquiry about limit switches, which are devices used in various applications to limit motion or control equipment based on specific conditions. The user may be looking for a definition, function, or applications of limit switches.
Answer
A limit switch is a device operated by motion or presence of an object, used in machinery control, safety interlocks, or counting objects.
In electrical engineering, a limit switch is a switch operated by the motion of a machine part or the presence of an object. It can be used for controlling machinery, as a safety interlock, or for counting objects passing a certain point.

More Information
Limit switches are commonly used in industrial applications. They are reliable because they physically detect position and automatically reset, providing a simple way to control complex machinery.
Tips
A common mistake is confusing limit switches with sensors or proximity switches. Limit switches require physical contact to operate, unlike non-contact-based sensors.
