I'm having a problem with my flippers which I'm pretty sure is related to the leaf spring switches they are using. I would like to convert to an opto board, my question is, what is the difference if I use this, https://www.pinballlife.com/fliptronics-1-flipper-opto-board-single-side.html or use these two together, https://www.pinballlife.com/fliptronics-type-2-opto-board-replacement.html and https://www.pinballlife.com/williamsbally-flipper-opto-interrupter.html .The second option is less than half the price. Would either of the two options work?
