Just a small job this, but satisfying nonetheless.
A friend is restoring a lovely old Jaguar but couldn't find replacement door switches at a sensible price, so asked me to make some for him. I had a worn example from which to copy main dimensions but could use different manufacturing techniques as required.
One of the four is assembled in this view. The body and plunger are turned brass, whilst the mounting plate is polished stainless steel. At the rear is a turned brass contact ring with copper connector lug. These last items are electrically isolated from the plunger on which they are mounted by two hard plastic discs, one inside the ring and the other adjacent to the nut and washer.
Originally these switches were only fitted in the front door apertures. Courtesy lights in the rear passenger compartment were controlled by the driver through a dashboard switch !! although this arrangement is being retained for authenticity, new switches are to be added to rear door openings for greater convenience.
