This New "green" Key float switch from Mac3 is gives you all the functionality of the original Mac3 Key. The only difference is that the body of this float switch is made from recycled plastic. Thereby reducing plastic waste and promoting the circular economy.

This is a double action float switch that can be used to either fill or empty a tank. Therefore can be used as a high level alarm switch, dry run protection of a pump and also control the water level in  tanks.

The Mac3 Level Regulators are a float switch that allows electrical equipment to start and stop automatically (usually pumps, but also solenoid valves, alarms, etc.) when a prefixed level has been reached.

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). It can be used for filling or emptying according to the cables that have been connected.

The Float is a double liquid proof chamber for maximum reliabilty.

Due to it's size, this Float Switch is the most versatile and can be used in most situations. It is a great general purpose Float Switch.

The switch angles are +45^o/-45^o.
