Pump / Control Panel Switches
TERMS TO KNOW

Pump Switches are used to directly control the operation of a pump. They are normally wide-angle switches which means they
operate over a range of approximately 70º to 90º. Pump switches are available with piggyback plugs and with bare leads. Some can
also be used with control panels.
Control Switches are designed to only control pumps when used with a control or alarm panel. They cannot handle the high 	
starting amps and running amperage of a pump, only signal or control amperage.
NO or Normally Open is a switch with contacts that are open in the hanging position. They are used to pump down or empty a tank.
NC or Normally Closed is a switch with contacts that are closed in the hanging position. They are used to pump up or fill a tank.
