Madison M9700 Liquid Level Side-mount Float Switch Spst

Product Description

The MADISON M9700 is a side-mounted liquid level float switch designed for monitoring fluid levels in tanks and reservoirs containing lubricating oil, hydraulic oil, gasoline, or diesel fuel. Built with a Kynar body for chemical resistance, the M9700 operates on a single-pole, single-throw (SPST) switching logic and is rated for 120 volts AC and 240 volts AC service. It connects via a 1/2-inch threaded fitting and is rated to a maximum of 100 psi and 100 degrees F. Electricians and fluid system technicians install this switch in industrial and mobile equipment fluid monitoring applications where a compact, side-entry mount is required.

The M9700 is suited for use in tanks holding lubricating and hydraulic oil, gasoline, and diesel oil. Its side-mounted design allows installation at a defined fluid level point on the tank wall, triggering the SPST circuit when the float rises or falls past the set point. This makes it a practical choice for low-level alarm circuits, pump control, and automated shutoff applications in both stationary and mobile fluid systems.

Key Features

• Side-mounted float switch design for tank wall installation at a defined level point
• SPST switching logic for straightforward low-level alarm or pump control wiring
• Rated for 120 volts AC and 240 volts AC operation up to 30 watts
• Kynar body construction provides resistance to fuels and hydraulic fluids
• 1/2-inch threaded connection for standard tank fittings
• Rated to 100 psi and 100 degrees F maximum operating conditions

Compatibility

Designed for use with tanks containing lubricating and hydraulic oil, gasoline, and diesel oil where a side-mounted, 1/2-inch threaded float switch with SPST logic is required.

Installation Notes

Installation should be performed by a qualified electrician or fluid systems technician familiar with applicable NEC requirements for the circuit voltage and environment. De-energize all connected electrical circuits and relieve tank pressure before installing or replacing the switch. Ensure the tank fitting is clean and that thread sealant compatible with the fluid media is applied before threading in the 1/2-inch fitting. Confirm float travel is unobstructed inside the tank before returning the system to service.
