Abstract
897,235. Change-over switches. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. March 25, 1959 [April 18, 1958], No. 10415/59. Class 38 (5). A heavy current changeover switch is actuated by hydraulic cylinders 11 having pressure accumulators 13 and operated by oil supplied past a solenoid valve 35. Depending number 20 is engaged by a finger 19 if the hydraulic pressure is too low for a satisfactory breaking operation, a relief valve 6 and overpressure warning device 7.
