Answer:
on or off
Explanation:
A switch can only exist in one of two states: open or closed. In the off state, a switch looks like an open gap in the circuit. This, in effect, looks like an open circuit, preventing current from flowing. In the on the state, a switch acts just like a piece of perfectly-conducting wire.
4 Types of Switches
Basic types of switches are SPST, SPDT, DPST, and DPDT.
How many switches can you have on a circuit?
It may be as shown at the end of the run, but it may be between any pair of switch boxes (as shown in a later figure), or even between the panel and the first switch box. You can use as many 4-way switches as you like.
