The F i g. 1 shows individual movement phases of the Crank 29 with the crank pin 31 and the rod 7 or the pivot lever 4 when opening and closing of the gate leaf. If the swing gate is closed, the crank pin 31 is on the right edge in Fig. 4a of the rod 7 and actuates the limit switch 44. The rod 7 actuates the limit switch 42. The gate leaf opened by hand, the rod 7 lifts from the crank pin 31 and pivots in Fig. 4a in
