Rocker Switches

Single Pole:This is the basic ON and OFF switch consisting of one input contact and one output contact. It switches a single circuit and it can either make (ON) or break (OFF) the load. The contacts of SPST can be either normally open or normally closed configurations.Dual Pole:This is a dual ON/OFF switch consisting of two ON positions. It has six terminals, two are input contacts and remaining four are the output contacts. It behaves like a two separate SPDT configuration, operating at the same time.
