A.C.T. will modify switches to provide the
best solution for your application.

Ordering Information:

Select a "Base switch Part Number", then specify a temperature switch set point (5°C - 140°C) and operation (open = "C" or close = "CR" on rising temperature) finally select the float switch operation (N.O. or N.C. with the float resting against the retaining ring).

A common hydraulic reservoir switch is "B 4030 N - 60 - CR - N.C." The temperature switch is open and will close (CR) on rising temperature at 60°C (140°F), and the liquid level switch is closed with the float against the retaining ring. If this float switch was mounted from the top of the tank the liquid level switch would be closed with an empty tank.
