Type of metal used for wiper park switch?

Does anyone know? I’d like to look into reproducing them.
Basically, they are conductive and only slightly malleable. They are springy and do not like to be bent very easily.

My thought is some kind of copper alloy like bronze?

Flat spring electrical contacts are most commonly made from Beryllium Copper, as it offers an excellent balance of electrical conductivity, springiness, and durability. Other common materials include phosphor bronze and brass, which are often preferred for their good electrical conductivity and cost-effectiveness, and can be coated to enhance performance. google

Beryllium Copper might require special handling, beryllium is bad news.

Phosphor bronze is brazing rod for cast iron. Buy it, heat it, roll or hammer the rods flat - annealing as you go.

This is awesome info. I’ll dig further
