Product description
The float switch consists of a switching contact in a waterproof float, which moves with the water level.
In the idle position, the contact is off and only at +5 cm water level is it activated.
This height is measured from the underside of the foot; the switch position is therefore determined by the installation height. Installation is easy.
This float switch contains no mercury or sensitive electronics.
Applications
Switching a pump
You can directly control a low-voltage water pump (12 or 24 volts) to automatically maintain the water level at a certain height: control range +/- 30 mm.
You can use this float switch to switch a bilge pump on and off, for example, to pump water out of a boat automatically.
Switching on or off
The mechanism of the float switch also works the other way round! If you mount it 'upside down', it can switch a pump or other device OFF when it reaches the maximum position. Again, a difference of about 30 mm between the off and on levels applies.
Water sensor with switching contact
The float switch can also be used as a detector for high water, e.g. in a basement or monitoring near a machine.
Especially in polluted water, the float switch acts as a reliable water sensor. Please note that at least 5 cm of water is required for an alarm signal!
Switch-on and switch-off point
This float switch has a hysteresis: the switch-on point is at approx. +5 cm and the switch-off point at +2 cm. Within these distances, measured from the bottom of the foot, you can therefore automatically control a water level.
