Description
The detection switch is an electromechanical device used to detect the internal mechanical movement or circuit state of the device.
They use magnetic fields to sense the distance from other components. They can then initiate operations, such as opening a door or locking a door latch. They can also detect circuit changes by monitoring frequency levels and current increases.
For mechanical movement detection, levers, buttons and plungers can initiate movement. For example, if you pull the lever on the garage door, the movement will be detected and the door will be opened.
In the circuit, when there is a voltage spike or a battery depletion signal, the switch will cut off the current or restore the current flow.
Detection switches can be found in consumer electronics, electrical appliances, networks, and instrumentation.
Type of detection switch
- Process switch can be used to detect physical variables such as temperature. If the temperature exceeds a certain level, the switch will sense it and then an alarm will usually be activated.
- The optical switch can emit a light beam to shine on the machine in the dangerous area. When someone walks by and blocks the beam from spreading, the switch will activate a security alarm.
