What is an electric switch answer?

Answer: (a) A device that is used to break an electric circuit is called electric switch. … When switch is in ‘OFF’ position, then the circuit is open i.e. no current flows through the circuit and when switch is in ‘ON’ position, then the circuit is complete i.e. current flows through the circuit.

What is an electric switch in short answer?

Electric Switch is an electrical device which can make or break an electric circuit. A switch is said to be in ‘ON’ position when it makes or completes the circuit and allows the current to pass through. Similarly, a switch is in ‘OFF’ position when it breaks the circuit and does not allow the current to pass through.

What type of switch is this?

The simplest type of switch is a single-pole, single-throw (SPST) device that functions as an on-off switch. Double-pole, double-throw (DPDT) switches are commonly employed as internal polarity reversing circuits. Switches of up to four poles and three throws are common and some have breaks.
