I'm just posting this as an FYI in case anybody else encounters this
problem.

Recently, we shutdown a Bruker cryoplatform for a planned power outage in
our building. Upon trying to restart, the power button would not engage. I
would push it, the lights would turn on, but upon releasing the button,
power would be cut again. The contact block for the power button had
failed. It was a fairly cheap/simple repair, though a bit tricky to remove.
The part description says "lifecycle of 1 million switching cycles" so it's
possible that I am the only one who will ever encounter this problem, but
in case somebody else does, here is the part info and a link to it at
