The load current of the microswitch depends on the switch model and application scenario. In general, the load current of the microswitch is between a few milliamps and a few amps.
I. Concept and measurement method
Micro switch is a common type of switch, widely used in industry, automotive, electrical, communication, instrumentation and other fields. The load current of the microswitch refers to the current through the switch contact, and this current is stable when the switch is working normally.
Measuring the load current of a microswitch requires a multimeter or ammeter. The specific steps are as follows:
1. Disconnect the load circuit of the microswitch.
2. Use a test pen to connect the pliers of the multimeter to the two contacts of the microswitch. Ensure that the connection sequence is correct to avoid short circuit.
3. Turn the knob of the multimeter to the current gear, so that you can read the current passing through the microswitch.
2. Typical load current values of different types of microswitches
Different types of microswitches have different load currents. The following lists the typical load current values of several common microswitch models for reference:
1. Small micro switch: usually the load current does not exceed 5A.
2. Medium micro switch: the load current is generally between 5A and 20A.
3. Large micro switch: the load current can reach tens of amps or even higher.
It should be noted that the load current size of the micro switch not only depends on the model and specification of the switch itself, but also related to the application scenario, such as the circuit operating voltage, load state, environmental temperature and other factors will affect the load current size. Therefore, in practical applications, it is necessary to select the appropriate microswitch model according to the specific situation, and install and use in strict accordance with the manufacturer's specifications.
