A permanent magnet

Œ

is attached to a pivoted

switch actuator and adjustment screw



. As the

float

Ž

rises following the liquid level, it raises the

attraction sleeve



into the field of the magnet,

which then snaps against the non-magnetic

enclosing tube



, actuating the switch

‘

. The

enclosing tube provides a static pressure boundary

between the switch mechanism and the process.

On falling level, a spring retracts the magnet,

deactivating the switch.
