switch has pigtail to silver wire?
I replaced a one way switch recently. The junction box has pigtails to some smaller silver wire, which is connected to the switch. 2 black wires, the neutral is just connected to another neutral in the junction box but doesn;t connect to the switch.
Is this ok? I read somewhere you shouldn't mix aluminium with copper?

Not all silver wire is aluminum. It could be tin covered copper which needs no special treatment.
If you can do so easily, file or scrape the extreme end of the wire. See if copper color shows through.
If it is aluminum, the connectors need to be a special kind for use with aluminum. Usually the kit comes with a tube of jelly to cover the exposed wire with.
The aluminum connectors will work with copper to copper joints although this is expensive overkill.

I noticed a lot of thermostats and baseboard heaters come with this same silver wire so it must be modern and up to code?

The are the silver with small wires/filaments...easy to wrap around a stiff copper wire.

That would be tinned copper. Look at a cross section.
