Check out these Jerguson® Magnicator® Magnetic Level Indicators headed to a company in Central Ohio! These Magnetic Level Indicators are equipped with SAS-16™ Snap-Action Switches.


How the SAS-16 Snap-Action Mechanism Works

The switch mechanism is based on a unique Jerguson tri-magnet design, where the snap action is accomplished through magnetic repulsion. The magnet mounted in the float causes a secondary magnet to rotate as the float passes up and down. The switch magnet is repelled by the secondary magnet and snaps to the opposite side - this causes the cradle to pivot, moving the push rod that operates the switch contacts.

The result is positive snap-action interlock switching: no springs, no cams, no problems.


Why "No Springs, No Cams" Matters for Reliability

Springs and cams are exactly the kind of mechanical components that wear out over repeated cycling - springs lose tension over time, and cams develop wear at contact points that can eventually affect switching precision. By generating snap-action switching through magnetic repulsion instead, the SAS-16 avoids these wear mechanisms entirely. There's no spring to fatigue and no cam surface to wear down, which is exactly why this design holds up well in applications with frequent level cycling.


Why This Matters for an Industrial Company in Central Ohio

Industrial facilities running continuous or frequently cycling processes place real demands on switch reliability - a switch mechanism that degrades gradually from mechanical wear can become a source of unreliable alarm or trip signals long before it fails outright. Specifying Magnicators equipped with SAS-16 switches addresses this at the design level, rather than relying on maintenance schedules to catch wear-related switch degradation before it causes a problem.


Applications

SAS-16 Snap-Action Switches on Magnicators are valuable across:

  • General Industrial Applications: Frequently cycling level switch service where mechanical wear is a real concern

  • Power Generation: Feedwater, condensate, and process tank level alarms

  • Chemical Processing: Reactor and storage tank level switching requiring reliable long-term operation

  • Any Application Requiring Positive, Repeatable Switch Action: Without the maintenance burden of spring- or cam-based mechanisms
