LS FLOAT NO
Float level switch NO
A float-operated NO level switch changes contact state through a float mechanism at a documented fluid level.

Schematic · LS FLOAT NO
What it represents
The float-operated NO form connects a discrete electrical action to a defined liquid-level mechanism. The drawing must identify the vessel or location and the direction of level movement that actuates the contact.
This is a convention-specific lookup based on the publisher's IEEE-labelled preview. The geometry here is independently drawn to explain the connection or operation; it is not a certified reproduction of the standard graphic.
How to read it
- Match the electrical reference state to the documented float orientation.
- Read the selected library and the project legend together. A vendor block identifier is meaningful within its named library and is not a universal standard-symbol code.
Information to show or reference
- Name vessel/location
- State level direction
- Reference operating/reset levels
A distinction that matters
Float level sensing is different from a continuous analog level transmitter.
