This is a Medium version of the currently out of stock Tact button. We designed and made this one for our box to be able to take the SXmini J V2 chip. Note the dimensions as these are different than the other buttons and make sure you can use them!!!
Use these as the needed extension for the on-board buttons of the J chip.
