Pneumatic adjusting cylinder

If the cylinder is controlled by electronic control; Then the wires of the two electrical switches (or buttons) are connected in series; And is connected to a pneumatic solenoid valve. In other words, two switches (or buttons) must be turned on/off at the same time, and the current will move the cylinder by controlling the solenoid valve.

If pneumatic control is used to control the cylinder, the control gas pipes connected with two gas switches (gas buttons) are connected in series and supplied to the gas control valve. That is, only by pressing (or pressing) two gas switches (gas buttons) at the same time can the air flow move the cylinder through the gas control valve.
