Replacing Swytch 4 Pin brake sensor

[mamucium79]

Hi

First post. I don't think this question has been asked. It's essentially a wiring question.

I have an original Swytch kit and want to replace the inline brake cable sensors with hydraulic sensors.
The swytch cables are blue-ended 4 pins but online all I can find are yellow 3 pins for similar sensors. (swytch don't seem to offer replacement parts btw).

Is it straight forward to cut the end off my 4 pin cable and splice to a new 3pin sensor cable ? Obviously one pin would be missing. I'm not sure what swytch's fourth pin is for, if other manufacturers only offer three.

Thanks in advance.

Look at the sensor and the cable as well as the connector. What's going on inside?

Is the cable a four core, or just a three core? Is the sensor a hall sensor, or some kind of switch?

I don't have one to look at...

Hope this might help. Using a spare Swytch brake sensor I chopped the the connector off to expose four wires and used three of them to link to an experimental lash-up on my folding bike with a different controller which required the brake sensor signal to go low when operated. My recollection (taped and insulated now so can't check) was that two of the wires were for 0 and supply (eg 5V) and the other two gave alternative modes for the operating signal ie low to high and high to low - the latter being what I needed for the alternative controller. So in my case the blue wire was not used. Peter
