Relays are the switches which aim at closing and opening the circuits electronically as well as electromechanically. It controls the opening and closing of the circuit contacts of an electronic circuit.17 Oct 2019
What is a relay switch and how does it work?
A relay is an electrically operated switch. They commonly use an electromagnet (coil) to operate their internal mechanical switching mechanism (contacts). When a relay contact is open, this will switch power ON for a circuit when the coil is activated.

Is a relay a switch or a load?
A relay is an electrically operated switch. Relays are used where it is necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled by one signal.
What is the difference between switch and relay?
You are correct that a relay is basically just a switch, but it's a switch operated via remote control, so to speak. A regular switch controls electrical current by connecting or breaking the path of either the positive side of a circuit (most common) or the negative side of a circuit.12 Jun 2019
What does DPST mean in electrical?
SPDT rocker switch. Dual ON-OFF. Double Pole, Single Throw = DPST. A pair of on-off switches which operate together (shown by the dotted line in the circuit symbol). A DPST switch is often used to switch mains electricity because it can isolate both the live and neutral connections.
