Hello Gentlemen and Ladies.
That DIY fever, has once again struck me. But alas, im in need of your help/assistance/guidance/knowledge - you get the point.
The question in spe, is how to change an old "turn" style contact, to a more modern "rocker" type.
Its from the donor deck, on wich i currently work - Technics sl-23. On the table, theres a "turn" style knob selector, for 33/stop/45 .
I must admit, i am a total noob, regarding switches. Especially toggle switches, witch i want to use - so i need to learn a lot :-] Thous asking you guys.
This is the switch in question
Now, the knob style switch, has 2 sides, with 4 pins on each. Only 3 are used though. If we number the pins, itll look like this:
Side 1:
1
2 3 4
Side 2:
5
6 7 8
Side 1, ive traced like this: Pin1=White wire, going to motor control board, Pin2=Red wire, going to potmeter1, and then to motor control board, Pin3=Unused, Pin4=Blue wire, to potmeter2, and into motor control board.
Side 2, Pin5=Brown wire, going to power board, Pin6=Grey wire, going to Pin8, Pin7=Unused, Pin8=Grey wire going to Power board.
So here goes: What switch (toggleswitch) do i need to replace this??
What im figuring is this: Theres 3 positions on the switch - one side==33 rpm, middle = stop, other side=45. would a 6 pins on-off-on switch do the trick?? Meaning that originally the 2 out of 8 legs are unused, or the configuration of the switch is different.
Im all confused about the kind of different toggle switches, (ON)-OFF-ON, or the other variations, with or without the Parenthesis. 1-2-3 or more Pole allso confuses me. Can you help me out :-]
More pics of the beast:
Thanx for all the help in advance, ill post elsewhere when the build (and photos) is ready...

You need a DPDT center-off switch. Also called ON-OFF-ON DPDT.
Make sure you DON'T get the momentary type with a spring return to center in it.
Some examples of what you need:

Thnx for reply 🙂 My thought was, that since its a 8 legged and only 6 og Them is used, maybe the number 1 and 5 pins is allways on ??
You can use a meter to check the switch out of circuit.
It's likely two ganged 3 position switches, with the center position unused.
