Control safety block for high pressure cleaning devices with switching device

摘要

The regulating safety block comprises a switching device (1) for a high pressure pump, a micro-switch (17), and a switching cam (18) which is actuated by a switching arm (2) by the displacement of a spring (3). The high pressure of the high pressure pump is acted upon the control piston (4). The actuation of the micro-switch is carried out through the free end of the switching arm, under the load of a compression spring (14) which is slidably mounted on an actuator (10).
