摘要
A switch mechanism serves for changing over the path traveled by a rail vehicle on a track. The switch mechanism has an electric motor, the rotational movement of which is converted into a linear movement by way of a spindle rod or toothed rack. Part of the mechanical system is usually also a coupling, which prevents excessive force from being exerted on the track. A flexible adaptation for the test slider of a switch drive enables complete testing of the switch drive on a test bench. The switch drive can be tested in the final state because the test slider does not need to first be removed and then reinstalled only after testing. Separate testing of the test slider in terms of its function and its high voltage strength is therefore no longer necessary. After the testing, no additional steps need to be carried out on the switch drive.
