This is a chassis, snap clasp, and plungers for a captive 12mm Tactile Switch. Designed to be integrated into panels where buttons are needed, but a PCB may be too large. This is designed to be added to your own design.
Plunger Shaft lengths are 4mm, 6mm, 8mm & 10mm.
I've added the design files in addition to the STLs, so that modification may be easier. This was designed with 123d.
