Water Level Sensor Liquid Float Switch Tank Pool NEW

Does the job great, be prepared to make an angle bracket with a hole big enough for the switch body

I wanted this to activate a bilge pump in my boat. It is light, impervious to salt water and the other things one finds in a bilge such as oil and fuel etc. The leads are long enough to reach above the likely level of water so the connections to the pump can be made in a dry location. So far, so good.

waste of money. this is my second sensor. the first works when it wants, which put the pump at risk from running dry. the second doesn't work at all. the low price doesn't justify the effort to return the product.

Arrived on time well packed and at a very good price.Tested ok, this sensor can be used to monitor liquid levels both high and low; just requires float to be removed and inverted.

I use one of these to switch a power transistor to drive a pump that refills my toilet cistern from rainwater tanks outside. It has been working flawlessly for a year.

Sorted my issue out on water pool heater just had to wedge the water sensor as it worked oppersite to what i thought but it worked
