Check the listing for details. Nintendo NES Quiet Softer Zapper Light Gun Microswitch Kit Bracket. Color: Black, Condition: Open box. Listed at 10.00 USD. PICTURED LIGHTGUN IS NOT INCLUDED AND SHOWN ONLY FOR ILLUSTRATION OF INSTALLATION After purchase contact me and I will send the installation guide if you need it. This kit is designed to remove the noisy spring recoil of the Nintendo NES Zapper. It gives the trigger a softer, lighter touch and quiets the gun considerably. A brand new microswitch, 50 gram actuation force, is included with this kit. As this is a DIY alteration, it is the buyer's responsibility to know what they're doing. I can provide help by messages if you have any questions. Currently I am manufacturing with black plastic, but that may change to a different color if I run out. Note that there could be some dimensional variance in the injection molded parts that the 3D printed parts fit into. You may have to perform some filing or use a razor/sharp knife to widen holes if things are too tight. I design these kits to be snug as it's better to have excess material instead of 'not enough.' The NES Zapper already has a microswitch inside, but it is a harder clicking switch and old. By circumventing the spring recoil of the trigger action you can fire the gun more rapidly, accurately and smoothly. You just run wire from the common and normally-closed tabs of the new switch to where the original switch was. I also have microswitch kits available for a variety of different video game lightguns ranging from Sega, Nintendo and Sony! I will combine shipping!
