Float switch normally open

So we would like to clear things up. When we say normally open or normally close we are referring to an electrical circuit. An open circuit is incomplete, meaning that the electric . The rising action of the float can either close (i.e., turn on) a “ Normally Open ” circuit, or it can open (turn off) a “Normally Closed” circuit.

VAC, 10A, Wire Leads, -, Top Stop, Bottom Stop, 2HXZ4.

Degrees Below Horizontal, Degrees Above Horizontal, 3BY74.

A Pump Up opens the circuit on the rise.

For horizontally mounted float switches , the float switch assembly can be rotated 1degrees for normally open or normally closed operation. Allows the pump plug to be plugged directly into this plug. A “Pump Up” float switch opens the circuit on the rise.

A “Pump Down” float switch closes the circuit on the rise. Float Switches – Understanding Terminology. Sometimes the terms “ Normally Open ” and “Normally Closed” are used to describe float switches. Liftstation Parts, Components - How they work.

The bottom switch will be closed provided the liquid is above that switch point. The liquid rises until the top float switch closes and energises the relay. One set of relay contacts connects the pump to the . We supply both normally open and normally closed versions for top, bottom or side mounting. The majority of our stocked products have . Mechanically-Activate Narrow-Angle Control Switch. Control switches accurately monitor liquid levels to activate pump control panels and alarms.

Normally Open Models ( high level): The control switch turns on (closes) when the float tips slightly above horizontal . This protects the virtually unbreakable, hermetically seale stainless steel mercury switch bulb. The avocado shape and smooth, debris-shedding surface assure reliable operation in the worst lift station conditions. It signals the pump to turn on when your water reservoir is low and off when the reservoir is full.
