Description
A roll up door switch is a type of switch that is used to control the operation of a roll up door. Roll up doors are commonly used in commercial and industrial settings, but they can also be found in some residential applications.
There are two main types of roll up door switches:
- Magnetic switches:Â These switches use a magnet to open or close a circuit. When the magnet is close to the switch, the circuit is closed and the door can operate. When the magnet is moved away from the switch, the circuit opens and the door stops.
- Mechanical switches:Â These switches use a physical lever or button to open or close a circuit. When the lever or button is pressed, the circuit closes and the door can operate. When the lever or button is released, the circuit opens and the door stops.
