These are an upgraded version of those I used to sell. Always seeking improvement and although these cost more they have a longer mechanical life up to 20000000 cycles at 95% survival. We were finding the cheaper switches are starting to fail particularly on AMI when used as stopping switches.
- BIG BLACK MICROSWITCHES = as used by AMI as there mechanism stopping switch AND by Rock Ola on there earlier machines Cam switch cluster AND in various models of 78 rpm machines.
N.B. Always need replacing if not already replaced.
