## Description

**Float switch Key, 4 A, 3 m, yellow** is a float switch by MAC3 (Italy). It switches a pump on or off by water level, protecting it from dry running or stopping a tank from overflowing.

Key specifications: cable length — 3 m and max. current — 4 A.

### Where to use it

- dry-run protection for borehole and drainage pumps
- automatic filling or emptying of a tank
- level alarms in tanks and sumps

The switch can power the motor directly if the pump current is within its rating; larger pumps need a contactor.
