Re: Wiring Diagram for 8 pole 5 way Strat Switch?
That, my friend, is a two-pole switch. Contacts 1-4 are the first pole. Contacts 5-8 are the second.
The jumper connection between 4 and 5 forms the combined output to a master volume control.
The connections made between contacts 2 and 3 and then, contacts 6 and 7 are as per a budget Telecaster three-way selector. The legend 3P printed on the plastic is a bit of a giveaway. The switch can function in a Stratocaster but you will be forever performing the vintage switch lever balancing act to obtain positions 2 and 4.
For a Stratocaster application, remove the jumpers between 2/3 and 6/7.
1= Bridge PU
2 = Centre PU
3 = neck PU
4 = output
TRADITIONAL SECOND POLE WIRING
5 = traditional link for tone controls
6 = Bridge PU tone connection
7 = Centre PU tone connection
8 = Neck PU tone connection
AUTO COIL SPLIT HSS/HSH WIRING
5 = no connection
6 = Bridge PU coil split wire
7 = Ground
8 = Neck PU coil split wire
Personally, I would save time and trouble by not economising on the selector switch. The price difference is worth less than my time for having to resolder everything a second time in six months.
