M Series
Tilt Float Switch

Madison Company's Tilt Float Switch is an inexpensive, efficient and highly reliable level detector for open vessels, sumps and ponds.

The molded rubber float has an integral three conductor cable and operates on a micro-switch device that is located inside the float on an anti-vibration mount.

The rubber float is constructed of ethylene propylene diene (EPDM), a synthetic rubber with rigid and durable characteristics for long service life and resistance to heat, oxidation, ozone and aging due to weather. As a non-polar elastomer, EPDM has good electrical resistivity, as well as resistance to polar solvents such as water, acids, alkalies, phosphate esters and many ketones and alcohols.

The basic operating principle is that as the fluid level rises the float will rise, causing the micro-switch to tilt and generate a signal that can be used to start or stop a pump, open or close a valve or actuate indicator alarms as required.

Float travel is approximately ± 45° arc from its nominal position..

There are no specific installation concerns. However, the lead cable should be supported in an enclosed tank. Additionally, in an open tank, sump, or pond, it is advantageous to clip the lead cable to the side, especially if excessive turbulence is experienced (a nylon cable-tie is included).

To alleviate the effects of rapid switching conditions if such turbulence is expected, it is recommended that a maintaining circuit be used to both safeguard the micro-switch and cut out any chatter from the starters of associated equipment, such as pumps.

An optional stabilizing weight and rubber "O" ring are included with the M4189 Tilt Float Switch. This may be installed at any point on the lead cable.
