You are purchasing a NOS (New Old Stock) choke warning switch on the cable for the Triumph TR7 (all), Stag (all) and 2000/2500/2.50PI, Dolomite and Sprint.
This is sealed in the package and has a very small set screw on the clamp so we did not open this to photograph. Photo 4 is from the TR7 parts page.
Shown as no longer available from the common suppliers.
At the time of this listing we had multiples available if you'd like a 2nd switch, no extra shipping needed.
New from a vintage inventory, marked made in UK, part number 137607. {B W}
Photos are the actual part.
Please see our auctions and ebay store for more NOS new and one of a kind parts.
Thanks.
