  • Selectable switch function adapts to tank requirements
  • SPST contact form handles 240 VAC at 0.28 A

SPST Liquid Level Switch for Tank Monitoring

The Madison M9705 is a side-mount SPST liquid level switch designed for tank installations. It operates at up to 240 VAC with a 30 VA rating and a maximum pressure of 100 psi. The Kynar body, stem and float resist corrosion in harsh fluids. CE, NSF and UL listed standards support industrial and commercial use.

Verify Tank Fitting and Electrical Rating Before

Confirm the tank connection matches the 1/2 in x 1 in NPT conduit size and side-mount orientation. Ensure the circuit does not exceed 0.28 A at 240 VAC and that the fluid temperature stays within the 221 degrees F maximum. The float diameter is 0.65 in and overall length is 4 in for clearance planning.

Replaces Failed Side-Mount Level Switches

This unit directly replaces worn SPST switches with identical mounting and electrical specs. The jump is worth it when the original float or stem has degraded or when certifications such as NSF are newly required. It is not suited for applications needing SPDT action or higher current loads.

Questions about this item

Does the M9705 come with mounting hardware or must I supply my own fittings?

The switch includes the Kynar stem and float assembly; you must provide the 1/2 in x 1 in NPT tank connection and 1/2 in conduit fittings separately.

Should I choose the SPST version or look for a different contact form?

This model is only offered as SPST selectable, so choose it when you need a single-pole single-throw switch that can be wired normally open or normally closed.

What does the 30 VA rating mean for my 240 VAC circuit?

At 240 VAC the 30 VA rating limits the switched current to 0.28 A; stay below that load to avoid exceeding the contact rating.
