LS-3 46999 – Compact Type Bottle Level switch

The LS-3 46999 compact bottle level switch is ideally suited for external mounting on tanks too small to accommodate internally mounted switches.

Principle

When the magnetic field of permanent magnet inside the float is moved into to the proximity of the reed switch inside the stationary stem, the reed switch contacts “snap” together and closes the electrical circuit. When the magnetic field is moved away from the reed switch, the reed switch contacts move apart and the circuit is opened.
