The electrical switching and operating relays are common parts in electrical motor and installation systems. Electrical relays are used to switch large or different currents on or off via a relatively small current, often as a multiple of the control current. This is to eliminate heavy cables and to avoid unnecessary strain on contacts. In fact, a small switch is used to switch on a larger one by means of a magnetic coil and a contact.
The contacts are made of copper or silver. Silver contacts are more suitable to handle high currents.
As a rule, the control voltage used to turn on the relay is mentioned first, e.g. 6v, 12v, or 24 volts. This is followed by the maximum current in amperes to turn on the relay.
A so-called mini relay can usually only switch on a maximum current without surges. As the names suggests, operating and high-power relays are more designed for heavier jobs, often indicated with a second maximum amperage (short/long). For example, by switching a motor on, a power surge will occur for a short period of time.
