What type of switch is represented by component 3 in figure T-2?
Pick an answer to check it.
Answer: A. Single-pole single-throw
Component 3 in Figure T-2 is a simple switch: one moving arm with one contact it can close against. One pole and one possible connection make it single-pole single-throw (SPST), a basic on/off switch.
Tip: One arm, one contact: SPST, a plain on/off switch.
