HQ-Series is a float-type level switch, which is solid and easy to use. It is designed
to control different liquid levels in boilers as well as water treatment and other
industrial facilities.
■ Mercury Switch
As the liquid level rises, the float also rises because of its buoyancy thus causing it to ti
lt. As such, the mercury inside the float flows to the terminal to connect it as a contact.
■ Micro Switch
As the liquid level rises, the float also rises because of its buoyancy thus causing it to ti
lt.
The metal ball inside presses the micro switch to make contact.
