Fig.14.12 shows how limit switches can be substituted for pressure switches to control the operation of a double-acting hydraulic cylinder.
RECIPROCATION OF A CYLINDER USING LIMIT SWITCHES Fig.14.12 shows how limit switches can be substituted for pressure switches to control the operation of a double-acting hydraulic cylinder. Figs. 14.12(a) and (b) show its corresponding hydraulic and electric circuit diagrams respectively. The sequence of operation and control capability are exactly the same as that of the system discussed in Section 14.5.2, except that each pressure switch is replaced by a normally open limit switch.1.
