The MBC pressure switches are used in marine applications where space and reliability are the most important features.
The MBCs are compact pressure switches, designed according to the new logic of modular design to withstand the severe conditions of the notes engine rooms of ships.

They have a high resistance to vibration and have all the marine approvals required.
The fixed differential, but low, ensures accurate monitoring of critical pressures.
The valves to block MBV may be provided as a standard option for MBC pressure switches.

All relevant marine approvals
Microswitch to stroke reduced differential (fixed)
Resistant to shock and vibration
Diaphragm version for applications with pulse / pressure peaks
Easily to mount on the valve block
Available as differential pressure switch

To get the best performance from MBC pressure switches, it is recommended to put into practice the following standards:
