Liquid level switch for tank monitoring

The Madison MS5917 is a stainless-steel SPST liquid level switch designed for vertical open-tank mounting. It carries a 240 VAC rating and a 200 psi maximum pressure limit, making it suitable for industrial fluid-control applications. The unit uses a 1/4 in NPT tank connection and a selectable switch function for flexible wiring.

Fits standard 1/4 NPT ports and frees wiring choices

The 1/4 in NPT thread allows direct installation into compatible tank fittings without adapters. A 60 VA rating and 0.5 A maximum current support low-power control circuits, while the selectable contact form lets the installer choose normally-open or normally-closed operation. Stainless-steel stem and float resist corrosion in harsh fluids.

Replaces failed float switches in existing tanks

This switch serves as a direct replacement when an older vertical-mount float switch fails or leaks. The upgrade is worth it when the original component cannot withstand 482 °F operating temperatures or 200 psi pressure spikes. Buyers who need horizontal mounting, larger conduit entries, or multi-point level sensing will need a different configuration.

Questions about this item

Will the 240 VAC 0.5 A contact rating hold up under continuous cycling?

The SPST contact is rated for 60 VA at 240 VAC with a maximum current of 0.5 A, suitable for continuous duty within those limits.

Does the stainless-steel stem and float run hot during all-day operation?

The switch body and float are stainless steel and rated for an operating temperature up to 482 °F, so heat buildup in normal liquid-level service is minimal.

What tank fitting do I need to install the 1/4 inch NPT connection?

The switch mounts vertically with a 1/4 inch NPT tank connection and requires a matching female NPT port on the tank.
