A limit switch is an electromechanical device that consists of an actuator mechanically linked to a set of contacts.

When an object comes into contact with the actuator, the device operates the contacts to make or break an electrical connection. Limit switches , regardless of their final purpose, can only perform two functions.

Most limit switches that. Resistor - It just limits the flow of electricity to the fixture. Which changes the brightness or speed or volume ETC. The options with a universal remote are limited. You can (a) find the product you want to control on a code list supplied with the universal remote or possibly on a website, or (b) use an automatic process to program the remote to a. The actuator is the part of the switch which physically comes in contact with the target.
