Polypropylene Liquid Water Level Sensor Vertical Float Switch 100mm





A float switch is a device used to sense the level of liquid within a tank. The switch may actuate a pump, an indicator, an alarm, or other device.
The output wires are ‘Closed Circuit’ when the float moves to the end of the rod (away from the mounting fixture).
Made from polypropylene, so it will not rust.

product contains a Sub-Miniture reed switch, which are very reliable
BUT if the voltage or current ratings are exceeded the reed contacts
WILL fuse together this WILL permanently damage the unit.
Remember current produces the heat and voltage pushes the current. Power = Current x Voltage
*** The product will not be replaced if the reed contacts are fused together. ***
you are going to run a pump or high current device this should be done
using a separate appropriately rated relay and use the float switch to
turn on the coil of the relay still observing the voltage / current and
use a diode for back EMF protection.

If you are unsure about your switching current and your running current – Please do not purchase.

Every float switch is load tested before shipping.

I am making the above statement as some buyers have damaged the unit due to improper use.
