General purpose relays, or mechanical relays, are electric switches that open and close in line with an input signal, such as a voltage or current, which is applied to a coil. These devices can have input terminals for single or multiple control signals and sets of operating contact terminals. Essentially relays convert small electrical input into larger currents.
A major advantage of general purpose relays is that they are economical, helping reduce system costs.
