q Single pole snap switches that contain 2 double break contact elements (1 N.O. and 1 N.C.) must be used on circuits of the same polarity. Two pole snap switches contain two electrically
separated sets of contact elements allowing use on circuits of opposite polarity. Each set contains 2 double break contact elements (1 N.O. and 1 N.C.) that must be used on circuits of the
same polarity.
