Jerguson SAS-16 Point Level Switch

The Jerguson Magnicator II point level switches are fully adjustable and non-invasive. Switch points can be changed easily without any interruption to the visual indication or process.  The bias magnet design latches the switch maintaining the contact after the level continues to rise or fall.  All switches are mercury free and environmentally safe.

This switch mechanism is based on a unique Jerguson three dimensional magnet design where the snap action is accomplished by the utilization of magnetic repulsion. The magnet mounted in the float causes the secondary magnet to rotate as it passes up and down. The switch magnet is repelled by the secondary and snaps to the opposite side. This causes the cradle to pivot, moving the push rod which operate the switch contacts.Larger Image of Switch.
