From the mode of operation, the switch is divided knob type, plate moving type (including button switch, boat switch), button type; Most of the micro-switch knob and plate switch can be kept (locked) in the on or off state after operation, such as the daily use of light switches, fan speed switches, because there is an obvious direction of operation, so most of these switches do not need to emphasize whether self-lock.Only push-button switch when using is pressed, and most push-button switches are used to switch on or off the circuit when pressed, and the state is restored after release, Because this requirement can be achieved by using a circuit composed of a general button switch and relay, However, if only one relay (or contactor) is used, when the power switch button indicator light is pressed, the indicator light is on, indicating that the power is normally connected and the protector can be used normally; Otherwise, it cannot be used. The load current of the device protected by the micro switch should be less than 10A and cannot be used in excess of the load. If overloaded, the product will automatically disconnect the power supply.
1, the shell grade is higher, usually can reach more than IP44;
2, can be connected with the line slot and line pipe;
3, small capacity (can be equipped with functional parts);
4, the lightning protection component adopts the full protection mode of common mode and differential mode, and the selection of new technology and new technology is carefully developed.
5, strong flow ability, fast response time, residual low pressure.
6, temperature control circuit breaker technology and overcurrent protection technology.
7. Working status indication
