They're up for sale, but because every last one fitted to a car that's seen any kind of sunshine has broken like mine did, they are quite expensive.

Today, investigate this switch. Looks like previous owner discovered it was broken so used a toggle switch on a piece of speaker wire as the light switch for the car.

Le sigh. I might end up having to replace this if the shaft turns out to be too bent- looks like someone tried to remove the knob with a large pair of pliers without first depressing the little spring loaded button that allows it to be removed.

I don't know when flexible PCB made it to the scene, probably mid seventies.
This is hand drawn, resin board PCB, like you find in old radios. They started to appear in consumer stuff by the late fifties.
Nah, older than that. These dashes in the 1969-on Imps had a flex PCB.

Older than I thought.

Well, the headlight switch is comprehensively broken.

That bit isn't meant to be separate from the other half of it and it certainly isn't meant to be welded to that piece.

Those switches are peanuts from rockauto. Not sure how good they are as I sold both cars before much use after fitting them.

Yeah, under ten bucks. They're going to be better than what I have here. They're a common design, used for nearly 20 years so millions of cars were fitted with them.

I think the dash needs to come out soon, that'll get cleaned up and repainted.

Wiper motor switch. Thoroughly complicated, both in volume of pins and what it does with them.

There's commutator connections, field winding connections and a big rheostat to infinitely vary the motor speed.

That's all good and well, normally the wiper has maybe two connections, one commutator position and another at a different degree point around the shaft for a faster speed.
This one seems to do odd stuff- I have a feeling it's trying to ape the motion of old vacuum wipers... (Can't tell, don't have the wiper motor with the car, natch) where the arc they wipe is partial on the screen, then switch them off and they park themselves snug against the bottom of the window.
Reason I say that is that in the running position the field and armature connections are connected normally- one to power one to ground. Switch it off and it flips the polarity on the field, which makes the motor run backwards until it hits the park switch, disconnecting power.

Checked that and it seems to all work so I cleaned up the knob and escutcheon. Wiper motor is shared between a lot of Chrysler cars meaning it'll suffer from Charger tax. Fun times.

Dash is looking quite spartan. Pulled the rest of the turn signal lever out, that'll weld up.

Typically the switch is broken, as is common with this car.

The heater switch is also broken, bad design with it taking the full current of the fan and also the aircon compressor. This one melted. Thankfully they're available new.

Is it worth sneaking a couple of relays inline or are the new switches OK quality wise?
