Schuko igniter v1.2
This pressure fuse uses an L shaped body and lever arm the activate the fuse. The firing pin is kept under spring tension by a pin at the end of the fuse. To activate, the safety pin (smaller L shaped cylinder) is removed from the back of the igniter, and when ~40lbs of force is applied downward on the back end of the lever, the retaining pin is pulled up and fires the pin into the percussion cap.
This would primarily be used with the glass mine as a substitute for the buckzunder.
update: certain parts have had their thickness increased to reduce breakage.
