Wiring LGB 2-wire switches to 5175 Momentary Control Box

[Belly]

I have been attempting but with no success to wire turnouts properly so that they switch in both directions. The turnouts are the standard 2 wire (red & white) and I am using the 5175 momentary control box. Am I missing something? If I physically alternate the actual wires to the box I can make the switch go the other way. I have read that although the box has the 4 wire inputs you only need to use two of them to make a switch work. I am grateful for any input. Thanks!

You should be wiring an AC supply to the 5175. (normally black and white connectors on an LGB Power unit. If you use DC ( the red and blue connectors used for track supply) by mistake I believe it would lead to the situation you describe.

I totally concur doctor.

Here is a link to the instructions of the 51750 momentary switch box. http://www.champex-linden.de/lgb_pr...85256A17006A1A94/$FILE/51750_51800_072002.pdf

I have been given the 5175 I have picked the power off the track, I do get the flashing showing I have power to the points but no movements does it mean I have to go back to the transformer? Les

You should use an AC transformer such as LGB51090/5

Agreed - the input should be AC

the input for your 51750 should be white and black from 16v AC (the track uses DC) from the switch to the turnoutmotor you use the black and orange (red for you) connections.
if the 51750 has just one input, connect white - and let the black go directly from AC powerpack to turnout-motor.
