I also have DP350, and the switch did fail. While it's difficult to
find that exact switch, the cutout and connections are standard, and
there are lots of switches that will work. Be sure to get a switch
rated for at least the rating of the failed switch. And buy a few
spares.

My backup plan was to make a metal plate to mount a MIL-SPEC toggle
switch. These are heavy enough to never fail.
