The pump is switched off again with a time delay (approx. 5 seconds) as soon as the liquid level falls below the lower sensor surface. Simple installation thanks to compact design. Switching capacity: 12/24 volts, up to 20 amps. Product details

Level switch septic tank I use the level switch in a clear water pit. Works flawlessly. I particularly like the time offset. The pump continues to run for a few seconds.

Sump float.switch It sits in my waste water sump and turns the pump on when the level rises. Works perfectly but doesn't like oil in the water.

Product details

This completely waterproof and fully automatic bilge switch works with no moving parts or mechanical switch contacts. It is installed in the positive connection line between the bilge pump and the battery. Built-in electronics measure conductivity between three corrosion-resistant stainless steel sensors and switch the pump on as soon as the liquid level reaches the upper sensor surface. The pump is switched off again with a time delay (after approx. 5 seconds) as soon as the liquid level falls below the lower sensor surface. The delay prevents false starts of the pump and the backflow of water that may still be in the hose to the outboard side. Suitable for all 12 or 24 V submersible pumps or bilge pumps with a maximum current consumption of 20 A (12 V) or 10 A (24 V). Supplied without fixing material.

Note:
The float switch should be installed so that the water level at the pump and switch is at the same level. The base of the switch must be higher, but never lower, than the base of the pump.

partially functional

The switch's contact surfaces are quickly blocked by suspended particles, contaminants, and deposits, preventing it from shutting off.

If the switch is easily accessible, cleaning is quick, but in an inaccessible graywater tank, it's less pleasant.

Avoid

Either it doesn't activate, or it doesn't stop the pump. Sometimes, after rubbing the sensors, it works correctly for two hours, then doesn't activate again. I've reinstalled my float switch. It doesn't work in seawater or freshwater. I don't have any oil in my bilge.
