Question

Quizplus · Accepted Answer

Single-pole pressure switches are the most commonly used type of pressure switch. They have only one circuit and can either be normally open or normally closed. Most pressure switches are single-pole switches, meaning they have one circuit that is either open or closed depending on the pressure being sensed. However, there are also double-pole pressure switches that have two circuits that can be opened or closed independently.
