Parts / On/Off Buttons

Aftermarket On/Off Buttons

A small, purely tactile upgrade — none of these change how the board works, just how it feels (and looks) to turn the marker on and off. See Electronics for how the stock on/off actually connects to the board.

Stock on/off

Stock Ion sticker on/off next to a clear push-button on/off

A flat sticker-style membrane switch on the original Ion 1.0 (left) — functional, but easy to lose track of by feel alone, which is the whole reason this category exists. The clear push-button (right) is the style the Ion 2.0, XE, and Epiphany moved to stock — see the Power Button entry below for the version sold to retrofit it onto an Ion 1.0.

Newest page on this site: none of these three have been independently researched for current maker status or availability yet — sourced from a 2007–2008 community parts catalog, flagged for follow-up rather than left off entirely.

I stock hard-to-source parts on hand for restoration builds when I can get them — see Build Your Ion for what's currently available.
