Product Parameters
Microswitches are alarm-triggering devices, when the alarm detects an abnormal situation, it will trigger the alarm signal to be issued through the micro switch.
In many alarms, micro switches are also used to control the switching of the power supply. When the alarm is in working condition, the micro switch turns on the power so that the alarm can work normally; when the alarm detects an abnormal situation and sends out an alarm signal, the microswitch will automatically disconnect the power to prevent the power from being wasted.
In some advanced alarms, micro switches are also used to adjust the sensitivity of the alarm. By adjusting the pressure or stroke of the micro switch, the response speed and sensitivity of the alarm to abnormal situations can be changed.
