Level float SIGNALMASTER SPDT

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 wastewater applications.

Control differential of 4 cm above or below horizontal level

SPDT = three conductor cable with double level, can also be used with one level.

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 operate in either normally open or normally closed applications and is not sensitive to rotation.

Features
Can be wired to operate in either normally open or normally closed applications (single pole, double throw)
Mechanically actuated, snap acting contacts
High impact, corrosion resistant, polypropylene floating housing
Control differential of 1.5 inches (4 cm) above or below the horizontal plane
Green colored cover for easy identification of SPDT control switches

For normally open (high level) or normally closed (low level) applications
In standard cable lengths of 10, 15, 20 or 30 feet (3, 5, 6 or 10 meters) – longer lengths available

Two mounting options for installation flexibility:
Mounting clamp: for applications where the float can be attached to a discharge pipe or similar mounting device
Externally weighted: for applications where the float can be suspended from above
UL Listed, CSA Certified
Five-year limited warranty
