SJE MegaMaster™ Mechanically-Activated, Internally Weighted Control Switch

The SJE MegaMaster™ is a mechanically-activated, narrow-angle, internally weighted float switch designed for level control in municipal sewage pumping stations. The internal switching mechanism contains unique gold cross-point contacts, providing precision and reliable control signals up to 1 amp.

The SJE MegaMaster™ control switch can be wired to work in either normally open or normally closed applications. It is not sensitive to rotation.

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.
