Lower panel switches

[neal1980]

Hi,

I want to change the 3 switches on the lower dash panel. Has anyone used the switches from CBS I did a search but couldn't find much info on the wiring for these, I can see people have used them but no detail.

A search suggests the chimaera ones are double pole and they have 4 terminals but the ones below I can't get my head around how to wire.





Many thanks
Neal

DPST switches?

This webpage shows different types of switches

I've got couple block connectors knocking about,,,,,,

thanks for the picture I had already seen that but it still makes no sense to me

the original switches have 4 prongs.

Got the hazard sw from CBS 10mins with the meter and all is good
I think the old sw is DP that’s why it’s got 4 connections

Is it this one?

I was looking at this one as it has blue illumination which will match my race dash.

It says double pole but it doesn't have the 4 prongs which is confusing me to how I would wire it up.

Doesn’t make much sense to me either, I’m guessing your switching is between the 12 volt in and out terminals.
Doesn’t seem to be double pole.
The normally closed contact is confusing me, would have to check it out with them the switch configuration.w

You say the original switches have 4 terminals but don't say if all 4 are in use.
If only two are used then your choice of switch will work fine using just the +12v in and out terminals.
The LED terminals can then be used either to illuminate the switch (during ignition on or when sidelights are on) or to indicate the switch is on.

This is a DPST (Double Pole Single Throw) switch that switches 2 pairs of contacts on/off and the 2 pairs are isolated from one another


This is a SPDT (Single Pole Double Throw)


The contact arrangement of a SPDT switch is not often used for car circuits due to the NC contact not being required

This is good

Thanks for the responses.
I'm wondering now if the pics on there site are wrong..

As the options say


But the double pole pic posted earlier only shows 3 terminals plus the 2 for the led light.

Good thinking, worth a phone call
