Price on request
Pressure switch
Available on back-order
Description
The MST-2.5S is a compact, heat-resistant aircraft pressure switch designed to generate an electrical signal when a preset excess pressure level is reached in a system.
Within hydraulic and pneumatic systems, the pressure switch performs discrete signaling by opening or closing an electrical circuit in response to pressure rise of the working medium.
The device is widely used in aviation equipment, including helicopter hydraulic and pneumatic systems, as part of pressure monitoring and protection circuits.
The product is also known under alternative designations MST-2.5S, МСТ-2,5С, MSTV-2.5S, МСТВ-2,5С, which refer to the same product type.
