Abstract:
1. A mechanism for operating point switches, comprising: an actuator control assembly ( 1 ) which actuates two half-bars ( 2 ) for operating the point switches, each one of the two half-bars connected with one point switch by means of a device ( 3 ) for locking the point switches and by means of a manual control ( 4 ) connected with the actuator control assembly ( 1 ), characterized in that, the actuation of the two half-bars ( 2 ) for the operation of the point switches by the actuator control assembly ( 1 ) is carried out by means of rotational entrainment devices with cams ( 5 ), each one being assigned to a half-bar for operating ( 2 ), and comprising the placement of a first cam disk ( 7 ) on a vertical shaft ( 6 ), the cam disk ( 7 ) cooperates with the actuator control assembly ( 1 ) and with the device ( 3 ) for locking the point switches into position, and a second cam disk ( 8 ) cooperating with the first cam disk ( 7 ) and with the device ( 3 ) for locking the point switches for the release of the said point switches from locking into position, and a means for stabilization having a spring ( 9 ) which is coupled, on a first end, to the second cam disk ( 8 ) and is mounted, on a second end, in a pivoting manner to the casing ( 10 ), and a lever ( 40 ) for the control of the half-bar ( 2 ) for the operation of the point switch, which is likewise brought into rotation with the vertical shaft ( 6 ).
