The reverser switch is included in a customized Master Control Unit according to specification no. 618585, which is used to control the traction and brake effort of a rail vehicle.
This Mode selector switch has a flexible connecting element, serving for the mechanical interlocking between the Power-/ Brake Controller and the Mode selector Switch in this Unit.
General Description Mode- /selector switch
The separate Mode-/ selector switch module is located at the left hand side of the Power-/ brake controller. It includes a control lever to select the driving direction and/ or driving mode. It also includes a key switch to activate the whole Master control unit. All binary signals (switches) are wired up to a connector that is located at the end of a breakout cable.
Between the mode selector handle, the key switch and the power-/ brake controller a mechanical interlocking system is installed. This interlocking mechanism serves the purpose of avoiding erroneous operation of these components. Whether or not a component is interlocked depends on the position of the other components.
To provide the mechanical interlocking between the separated Power-/ Brake controller and Mode selector switch a flexible connecting element (called Flexball) is used.
