Finder Float Switch 1 Changeover 10 A Cable Length 5 m (72.B1.1.000.0501)

Liquid level control in tanks, sumps and reservoirs often fails because the switch cannot handle the electrical load or the cable is too short to reach the controller. The Finder 72.B1.1.000.0501 float switch solves this with a robust 10 A changeover contact and a 5-metre PVC cable, so you can place the switch exactly where the level must be monitored and switch pumps or valves directly.

Who is it for

Installers and maintenance teams who need a reliable, suspended float switch for emptying or filling applications in clean water, wastewater or light chemical solutions. It suits domestic sump pits, rainwater tanks, industrial process tanks and HVAC condensate trays.

Tips

For pump-down (emptying) applications, mount the float so the pump starts when the liquid reaches the high level and stops at the low level. For pump-up (filling), invert the logic using the changeover contact. Always secure the cable with a strain relief above the maximum liquid level and keep the cable bend radius larger than 50 mm to avoid damage.
