If a decompression occurs, the panels are opened either by an automatic pressure switch or by a manual switch, and the masks are released.
22.
Often a pressure switch will operate a relay or other control device, but some types can directly control small electric motors or other loads.
23.
Once the pressure switch monitoring main supply line pressure indicates a preset pressure in the line has been reached, the system is hydraulically closed.
24.
Where solenoids are fitted to the outputs of fuel tanks, these are also connected to the output of the tachometric relay or oil pressure switch.
25.
A pressure switch will have a differential range around its setpoint in which small changes of pressure do not change the state of the contacts.
26.
In the case of the 16 valve " ECU activates an oil pressure switch which pushes a sliding pin under the slipper follower on each rocker arm.
27.
The bomb team X-rayed the detonation device, located a hidden pressure switch and eventually disarmed the bomb while Marines continued to bring out victims from other areas.
28.
The contacts of the pressure switch may be rated a few tenths of an ampere to around 15 amperes, with smaller ratings found on more sensitive switches.
29.
A method for very rapid charging called in-cell charge control involves an internal pressure switch in the cell, which disconnects the charging current in the event of overpressure.
30.
Once the entire system reaches the required pressure, a pressure switch sends a signal to the controller indicating that grease has cycled through to all the distribution points.
