Check with a decent-size electrical supply shop for snap-type wall 
toggle switches.  Many of them are DC-rated.  Their designs date back 
to the old days when houses were occasionally wired with 115 volts 
DC (!).

One type I've seen now and again, even in the home-warehouse 
places, is the round surface-mount type.  These are often used to 
replace the old round turn-knob switches in houses built 70-80 years 
ago.  When I was old-house-hunting in Virginia a few years back, I 
often saw these (both turn-knob and toggle) in attics.

Because they're small and easy to mount, this type would probably 
work nicely for an EV.  

Of course you could also use a DC rated relay and a small switch on 
the instrument panel, which is what most EVers probably do.
