PRESSURE, VACUUM, AND FLOAT
SWITCHES
Type GAW—Sensitive Control Applications
9016GAW vacuum switches are provided with double throw contacts; normally open and
normally closed circuits allow these controls to be used for standard or reverse action
applications.
Standard devices can be mounted from the front with the bracket provided. Two
mounting screws are required for a firm attachment to any smooth, flat surface.
Allowance must be made for flange projection. Controls with Form F modification include
two mounting feet with 9/32" mounting holes on 3-3/4" centers. Range and Differential
adjustments are internal and exposed by removal of the front cover.
Maximum allowable positive pressure: 100 psig.
Diaphragms are oil resistant, nitrile butadiene (Buna N) rubber.

Forms E, F
The 9016GVG1 vacuum switch is a companion to the 9036GG and 9037GG float
switches commonly used on vacuum heating pumps. Electrical ratings of float and
vacuum switch types are equal.

[1] Add Differential to Range to obtain the operating point on increasing vacuum (within vacuum limitations). The differential increases linearly over its range.
[2] The minimum differential doubles with NEMA 7 & 9 enclosures.
