These bad boys are modified by a technician and tuned specifically for paintball markers. You'll not find another 50 gram micro switch anywhere on the open market that has equal care and quality as this one. These switches not only have a light 50 gram depression rate but have a very short stroke as well. You'll barely have to hit the trigger on these to activate the switch. The stroke is so short we suggest using a trigger such as the Dragon's Tail or Snapdragon that have a backstop adjuster so not to put any undue pressure on the internal spring. If you want a maximum edge from a light micro switch, this is by far your best choice.
