Hydraulic pressure switch

摘要

Hydraulic press switch moves the power flow between an actuating plunger (10) and a spring plate (12) via a ball bearing (11). Preferred Features: The ball bearing is arranged in a coaxial recess at the side of the spring plate which is partially closed by the corresponding end of the actuating plunger so that the ball bearing remains in the assembly position. The ball bearing has a diameter of 2-3 mm to achieve the optimum between the bearing function and the ability of assembly.
