SJE SignalMaster® SPDT
International Product
Description (English)
The SJE SignalMaster® SPDT control switch is used to accurately monitor high (normally open) or low (normally closed) liquid levels to activate pump control panels and alarms in water and sewage applications. It features a green colored cap for easy identification of SPDT control switch.
Normally Open Models (high level): The control switch turns on (closes) when the float tips slightly above horizontal signaling a high level and turns off (opens) when the float drops slightly below horizontal.
Normally Closed Models (low levels): The control switch turns on (closes) when the float tips slightly below horizontal signaling a low level and turns off (opens) when the float tips slightly above horizontal.
This switch can be wired to work in either normally open or normally closed applications and is not sensitive to rotation.
