Mechanically-Activated, Narrow-Angle Control Switch

signal master yellow and white caps

The SJE SignalMaster® 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.

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 open models have a yellow colored cap for easy identification.

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. Normally closed models have a white colored cap for easy identification.

This switch is not sensitive to rotation.
