Hydraulic pressure switches have various uses in automobiles:
1. To switch on a warning light if the engine´s oil pressure falls below a safe level
2. In dust control systems (bag filter), a pressure switch is mounted on the header which will raise an alarm when air pressure in the header is less than necessary to gain or decline energy beyond the set value
3. To control automatic transmission , torque converter, lock-up
