Abstract (en)
[origin: EP0389851A2] The possibility is offered for raising the switch tongue of the switch, and thus of displacing said switch in the particular direction without frictional engagement against the slide chairs and without the necessity of lubricating the slide chairs. The basic idea lies in fixedly connecting the holder (3) of the rolling apparatus to the fixed track of the tongue support (1) by means of a hook (15), a clamp (5) and screws (6), and the arm of the rolling apparatus (4), mounted rotatably with bearings (12) on pins (11) raises the switch tongue (2) as a result of the force of the compression spring (7) and with the aid of the arm pin (10) in the holder of the rolling apparatus (3). <IMAGE>
