                                • DC-Contact SO / SS

                                • The DC contact block is used for signaling and annunciation applications.
                                  The snap-action mechanism prevents slow contact opening when the plunger is operated slowly. Quenching of the arc that occurs with DC is supported by two-capacity permanent magnets.

                                  These are arranged so that the polarity can be ignored when connecting +/- cabling. However, the polarity of the quenching magnets must be noted when installing the contact blocks to prevent the magnets adversely affecting each other. Contact blocks in four different colours are available for polarity identification of the magnets when fitted.

                                  The contact blocks may only be installed on non-magnetically materials with screw, etc. made of
                                  non-ferrous metal.

                                  The self-cleaning silver contacts are designed for low switching frequency, low currents and voltages. Gold coated contacts can be supplied (approx 0,2µ), less than 42 Volt required. The screw connection M3.5 at the side is suitable for 2 conductors max. 2,5mm².
                                  The plug-in connection at the top 4.8 x 0.8mm DIN 46247.

                                  Several contact blocks can be plugged on the top of each other and operated jointly. The plug-type terminals are then only accessible on the top unit. The contact blocks can be provided with shock protection to DIN VDE 0106 Part 100.

                                                • Application
                                                  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.

                                                  Interlocking mechanism
                                                  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.
