The 20 Series (2 inch/51 mm dial) and the 25 Series (2-1/2 inch/64 mm dial) Swichgage models are diaphragm-actuated, pressure-indicating gages with built-in electrical switches. These switches exceed SAE standards and are used for tripping alarms and/or shut-down devices.
The Swichgage® was specifically designed to protect engines/equipment in oil field, marine, irrigation, construction and trucking applications to monitor engine lube pressure, water pump pressure, hydraulic pressure, air pressure, etc.

20P and 25P Series Swichgage
The gage pointer makes with an adjustable contact to complete a pilot-duty circuit.
20PE and 25PE Swichgage 20PE (was 20EO) and 25PE (was 25EO)
Features internal snap-acting SPDT switches, instead of the single pole/pointer contacts. When the switch closes on falling pressure, it becomes set, as pressure rises the switch resets.
20PABS and 25PABS Swichgage
Same as 20P and 25P with internal SPDT snap-switch for prealarm.
20P7 and 25P7 Lockout Swichgage
Same as 20P and 25P Series. They also include a front, semi-automatic lockout for startup override. This built-in device holds the pointer away from the contact on startup. When pressure exceeds the set point, the lockout is automatically disengaged (see bulletin in downloads for details).
