Visual / Electrical Switches monitor the condition of engine air filters, fuel filters or other low to medium vacuum/pressure applications.

The indicators are available in:

(1) single position where the indicator locks at one calibrated position and activates the switch once the predetermined set point is achieved;

(2) graduated position where the indicator progressively locks at multiple positions until reaching the calibrated final position and activates the switch once the predetermined set point is achieved;

(3) non-locking where the system vacuum/pressure levels are continuously monitored and activates the switch once the predetermined set point is achieved.
