How many Featherweight Power Perches and integrated A/V bays do you have, especially in 29mm and 38mm min diameter rockets? I would like to see your solution to adding a switch to those products in rockets that have already been built. I have a number of regular and carbon fiber rockets that use those products, and in spite of 20 years of experience flying rockets and being Level 3, I have not yet figured out how to easily do that in small rockets, especially those that were designed specifically for those products. As I'm sure you're aware, the battery plugs directly into either the Power Perch or the top of the integrated A/V bay. I look forward to see how you've solved this issue. And for what it's worth, it's interesting how solid state switches that have been used safely for years are now suddenly unsafe. Tony ps: your tone and suggestion to take up stamp collecting seems disrespectful and belittling to those of us who have made a large investment in time, money, and rockets that for years have been using what has been considered an acceptable solution, not to mention the vendors who have made significant contributions to our hobby. Just because it may not affect you personally, does not mean it is unreasonable for those of us who have labored under the impression that we were doing things correctly, and have now been told that we must modify years of effort, to try and understand why we were wrong. What changed that made solid state switches suddenly and immediately unsafe?
