    Hi

    I'm trying to swap out a small 3-way position sliding switch on a PCB with a bigger and more sturdy one.

    I am new to electronics and because of this I approached the task in a somewhat logic way: the small 3-way switch on the PCB has 8 legs, hence I would need to swap it out with another 8 legged switch.

    First I desoldered/removed the small slide switch and hooked up the PCB again.
    My test confirmed that the PCB with no switch attached to it was in "Center" mode

    I then wired up the replacement switch and soldered it on to the PCB

    Sadly this did not work as I had hoped:
    Left position work
    Center position work (but as the PCB by default is in "Center" I'm not too sure)
    Right position do not work - the PCB is in "Center" :(

    Soldered on like this (NOT WORKING):

    Do anyone know how I should connect the wires to the pins on the new switch to get this working ?

    Could it be that your original switch was a 2P3T, or a dual 3-way selector? 1 an 5 would then be the common, switching between the 3 other. The best is to check out the old switch to see how it is switching.

    Thank you for your reply.

    I'm afraid I not skilled enough to check small original switch properly, but you may very well be right about the 2P3T thing

    Thank you for your reply

    Could you possibly provide me with a link to a switch you think would solve this for me, at this point Im not too sure what I should be looking for o_O
    I'm looking for a switch that is bigger, more sturdy as it will be fitted on the outside of a cabinet.

    Brgds, Thomas

    I managed to pulle the small switch apart after all, and I believe this is how it work:

    I guess the question is this: what type of 3-position switch behave this way?

    Thanks for looking into this - 2k units should just about cover it :p

    Just to confirm: what I need is a 2P3T switch?

    I did some further testing and it looks like only pins 2, 3, 4 and 5 are used
    Do you know if a 4 pin switch of this type exist ?

    Thanks for the help guys, the 2P3T switch did the trick.
    I also managed to figure our how to get the Switchcraft switch working if anyone's interested
