200mm Liquid Float Switch Water Level Sensor Stainless Steel Double Ball
A part of the review has been auto-translated.
Very usefull to fill up tank with only one relay, see picture
Delivered to Switzerland within 14 days, very fast. The product looks very good. The welding is done nice. The upper float switch (near the thread) has the 2 red wires. The lower float switch has the 2 black wires. By changing the float containers upside-down, the functionality can get changed from Normally-Open (NO) to Normally-Closed (NC). Therefore this product is universal usable. I can fully recommend this product. Thank you.
On four lines, turn on with the float up above, turn down with the float below
Perfect for filling tank from low to high, to replace sensible electronic unit, see drawing
