Frequently Asked Questions (FAQs)

1. Why are electromechanical relays used?

The typical applications of electromechanical relays include motor control, automotive applications such as an electrical fuel pump, industrial applications where control of high voltages and currents is intended, controlling large power loads, and so on.

2. Which device is an electromechanical relay?

An electromechanical relay is an electrical switch that is typically operated by using electromagnetism to operate a mechanical switching mechanism.

3. What are the electromagnetic relays?

Electromagnetic relays are those relays which are operated by electromagnetic action. Modern electrical protection relays are mainly micro processor based, but still electromagnetic relay holds its place. It will take much longer time to replace all electromagnetic relays by micro processor based static relays.

4. Where are mechanical relays used?

The point of a relay is to use a small amount of power to switch to a large amount of power. Relays typically are used in modern household appliances such as hair dryers, kitchen appliances, and lights that need to be switched on and off.
