Regarding a special high and low level switch

At different heights on this sight glass, there are two devices each roughly the size of solenoid valves, with a clip holding each one to the pipe of the sight glass. It is said that these devices serve as level switches for detecting high and low liquid levels. I know from the pictures that this is indeed the case, but unfortunately I can’t figure out how it works. I seek advice from those who are more knowledgeable: could it be photoelectric sensors? Or something else? Someone on the second floor just mentioned electrical contacts, but these two racks of mine don’t come into contact with liquid at all
It’s impossible to confirm without a diagram, but it could be an electrical contact level gauge. When the liquid level reaches the corresponding position, it activates the corresponding electrical contact, allowing current to flow. Thus, it displays the liquid level or is used for control.
I’ll go check it; it’s a electrical contact level switch

It offers stable and reliable performance, allows for adjustment of the upper and lower limits, is very easy to install, and is not expensive. Please refer to the animation on the website of water level controllers: www.shuiweikaiguan.com
