The 20DP and A20DP Series (2 inch/51 mm dial) and the 25DP and
A25DP Series (2-1/2 inch/64 mm dial) Swichgage® instruments are

a built-in electrical switch. This switch is used for tripping
alarms and/or shutting down equipment. These gages are intended
to monitor and indicate oil, fuel or water filter restriction and

the filter, resulting in contaminants entering the system.
