Tell us more about the float contact closure. Materials? Design?

Great! The simpler, the more reliable!!! (and cheaper) Recently, my super-reliable auto top-off with two floats and an alarm broke down and stopped adding water. I didn't even notice how the return pump started sucking in air.

This is probably Tunze???? The more details, the less reliability... There are two components in this - a relay and a float.

I wonder who the manufacturer is and what model it is?

Can I buy a set?

Everything is fine, but: 1) judging by the photos, a float switch is used that directly controls (turns on and off) some pump or valve. Based on the two wires, it seems to be a break - short circuit of the phase or neutral wire. That's not good. It's still 220 volts. 2) if there is a refill, there should be an overflow protection. It is done in exactly the same way. A sensor for the upper position is connected in series with the lower position sensor (float switch). Nothing complicated. In summary: switch the control system to a lower voltage (12 or 24 volts) and add overflow protection. That's my opinion.

1 The float switches not the pump but the relay. The sensor is installed in the wall of the tank, the wires are not in the water. 2 If something malfunctions, it stops refilling, which is not dangerous. Added after 1 minute. It is possible.

Is that how, excuse me? And the sensor design. Industrial?

Lindsay

Yes.

No, I have a homemade one. But it's similar to a TUNZ. My weak point is the sensor connection ports and the quality of the soldering.
