The relay is an electronically controlled switch which is usually used as follows.

The relay can switch big currents remotely from a chain in which this current flows, allowing to use thinner wires and contacts of switches.

The relay can have more than one managing director of an entrance unlike the mechanical switch.

The relay can perform function of the timer, for example, to set an interval of work of screen wipers.

If the system operated by the relay fails also a cause of defect, perhaps, the relay is, listen to operation of the relay at the included system. If the relay regularly works, then you have to hear click at its inclusion. If the relay is serviceable, then the cause of defect is concluded in elements or the connecting wires. If the relay does not work, it means that it does not receive the main power supply or the operating impulse or the relay is faulty.
On the majority of the relay on the case of the relay the electric circuit and an arrangement of contacts of the relay is put.
