The switch can be opened and closed after energy storage

What happens when a switch is closed?

A closed switch allows the current to flow in a direct (low resistance) path. The terms “open” and “closed” are used to describe both switches and whole circuits. An open switch is one that has no continuity, meaning that no current can flow through it.

What happens when a switch is open in a circuit?

No current can flow if the circuit is broken, for example, when a switch is open in the circuit, current will not flow in any part of circuit as circuit is open and there is no closed path available for charge to flow.

Why is the normally closed held open switch shown open?

The normally closed held open switch is shown open in Figure 2 – 18. Although the switch is shown open, it is actually a normally closed switch because the movable contact is drawn above the stationary con- tact, indicating that something is holding the switch open.

What happens if a switch is not present?

If a switch is not present, current will not flow through the circuit. This is functionally equivalent to a switch always being in its “off” state. Without a switch, there is no way to complete the circuit and allow current to flow.

What happens when a switch is in the 'off' position?

When a switch is in the ‘off’ position, it blocks the electricity flow from entering the main electrical circuit, and the circuit becomes an open circuit. On the other hand, when a switch is in the ‘on’ position, it allows the electricity flow to enter the main electrical circuit and the circuit becomes a closed circuit.

What happens if a switch is in its 'off' state?

If a switch is always in its “off” state, then current will not flow. This is functionally equivalent to a switch being absent because it has been physically removed, leaving dangling wires or empty solder pads.
