The thermostat 161 641 is suitable for controlling or monitoring a fixed temperature when the application demands a round shape. The thermostat is tested in accordance with UL 873 and also specifically approved for use in drip coffeemakers.

A bimetal disc is used as a temperature sensing element. Irrespective of the thermostat mounting position, this disc is pressed directly against the mounting plate and can therefore react quickly to changes in temperature. As soon as the preset temperature is reached the bimetal disc operates and opens the electrical contact, interrupting the circuit. On cooling the disc snaps back into the original position, closing the circuit again.

The ceramic housing is largely closed and protects the switching mechanism against touch or dirt. It remains dimensionally stable even at high temperatures.

The thermostat can be fixed by means of a pre-mounted 2-hole bracket or a separate mounting clip.
