Product Description

Small Float Switch for Tanks

The Mac3 Level Regulators are float switches that allows electrical equipment to start and stop automatically when a prefixed level has been reached. They are generally used to control pumps, but can aslo be used to open or close solenoid valves or sound an electronic alarm if water levels are too low or high (depending on how the float switch is installed).

Inside the device there is a microswitch that, depending on the level of the liquid, opens or closes the contact that powers the pump.

These Float Switches come with a 3 core PVC cable (3x1) which can be used for filling or emptying according to the cables that have been connected.

Small size, 82 x 111 x 48mm, means that it is a highly versatile float switch which can used in a variety of tank sizes.

The shape and switch angles (+45o/-45o) also means that it works well in confined spaces where there is little room for movement.
