M Series Tilt Float Switches Madison Company’s Tilt Float Switches provide inexpensive, efficient and highly reliable level detection in open vessels, sumps and ponds. LL The molded rubber float has an integral threeconductor cable and operates on a micro-switch device that is located inside the float on an antivibration 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. M4189 Tilt Float Switch The basic operating principle is that as the fluid level rises the float will rise, causing the microswitch 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 in an approximately ± 45˚ arc from its nominal position.
