Introduction
In hydraulic systems, power is transmitted and controlled through pressurized fluid in a closed circuit, which is an important component of the system.
When the preset pressure is reached, the switch contacts act.
Hydraulic transmission pressure switch mounting surface
1 Scope
This standard specifies the mounting surface of the pressure switch and provides a reference for the standardized arrangement of pressure switches, hydraulic valves and mounting plates.
