The socket switch at home is an electrical appliance that we often use in our daily life, （gold brass pogo pin factory china）but sometimes we encounter some problems, such as socket or switch failure, at this time we need to test the circuit to find out the problem. Here are some ways to test the circuit.

First of all, we need to prepare some tools, such as voltmeter, wire pliers, screwdriver and so on. Then, we need to turn off the power, just to be safe. Next, we can follow the steps below to test.

Test socket circuit

First, we need to insert the two probes of the voltmeter into the two holes of the socket, (wireless test pins pogo pin)and then turn on the power. If the voltmeter shows that the voltage is 220V, it means that the socket circuit is normal. If the voltmeter does not show voltage, there is a problem with the outlet circuit and you need to check whether the wiring of the outlet is loose or whether the outlet itself is damaged.

Test switch circuit

If the outlet circuit is fine, but the switch fails, we need to test the switch circuit. First, we need to connect the two probes of the voltmeter to the two ports of the switch, and then turn on the power. If the voltmeter shows that the voltage is 220V, it means that the switch circuit is normal. If the voltmeter does not display voltage, there is a problem with the switch circuit, and you need to check whether the wiring of the switch is loose or whether the switch itself is damaged.

Test the continuity of outlets and switches

If the socket and switch are normal, but no current flows after plugging in the appliance, (Test Probes for ICT and FCT supplier china) we need to test the continuity of the socket and switch. First, we need to insert one probe of the voltmeter into the socket hole, and the other probe into the switch port, and then turn on the power. If the voltmeter shows 220V, there is good continuity between the outlet and the switch. If the voltmeter shows no voltage, there is a problem with the continuity between the outlet and the switch, and you need to check whether the wiring of the outlet and switch is loose or whether the outlet and switch themselves are damaged.

Overall, testing your home's receptacle and switch circuits is not difficult, requiring only a few simple tools and some basic circuit knowledge. However, when testing the circuit, we must pay attention to safety and avoid dangerous situations such as electric shock. If you're not sure how to test your circuit, it's best to have it checked and repaired by a professional.
