what was the earliest dip switch?

[Robert Leigh]

Having searched the threads, I see a few people with later 20's cars have likely abandoned the High Low switchpanel headlight function and just wired dip-switch to the high.

I'd like to know when the first dipswitch came in and what did it look like? i.e. was it the same as the Nippy, sort of cut off conical and strapped to steering column? Or was there ever a dash mount?

I have never seen a dash mount dipswitch on an Austin Seven, except as a later conversion. The column mounted switch came in with the double filament plus sidelight headlamps fitted from late 1932. 'Dip and switch' headlamps came for late 1933, with the same switch, and Rubies had a floor mounted dipswitch. I am open to correction on dates/models, but I think there were only the two types of switch.
