Model C Erg w/ PM2+ ON?OFF Switch will not turn on the PM

The only way that the PM will power up is if you pull the handle.

Any advice for troubleshooting the ON/OFF switch?

Yes all the button contacts need a clean with a cotton bud and some IPA.

Also clean the back of the keypad carbon contacts.

thanks Carl
that was the problem, working fine now
