The Seimitsu PS-14-DN-K are very similar to the PS-14-KN buttons. The plunger and surround on these buttons are translucent, are 27mm in diameter and come with a fixing ring to hold the button firmly in place when mounted in a control panel or fight stick.
These are the perfect button to use when modding a fight stick. The plunger can be disassembled and artwork can be placed under the lens cap. This button can be mounted in a material with a thickness up to 7mm with the included fixing ring and requires a 24mm mounting hole.
