Using a steel rod to reset the overload relay
A relay is an electronically controlled switch that is typically used as follows:
- a relay can switch large currents remotely from the circuit in which the current flows, allowing the use of thinner wires and switch contacts;
- a relay can have more than one control input, unlike a mechanical switch;
- the relay can perform the function of a timer, for example, to set the interval for the windshield wipers to operate.

To protect some electrical circuits (electric windows, door locks, headlights) an overload relay is used. If the current consumption is significantly exceeded, the automatic overload relay will briefly disconnect the consumer's power supply circuit, but to restore functionality, some overload relays must be switched on manually. To do this, remove the overload relay and insert a steel rod from the contact side into the reinstallation hole and press the lock until it clicks (see Fig. Using a steel rod to reset the overload relay).
If a relay-controlled system fails and the relay is probably the cause of the failure, listen to the relay when the system is on. If the relay is working properly, you should hear a click when it is turned on. If the relay is working properly, the cause of the failure is in the components or connecting wires. If the relay does not work, it is not receiving the main power or control pulse, or the relay is faulty.
