Source needed for Replacement On/Off Switch (prefer OEM)

I have an HPS10 Personal Scope with a broken ON/OFF switch. After searching the site, I was not able to find a Parts Procurement Area nor was I able to find an eMail address for Velleman Service/Parts. I did not open the device yet, hoping to source a switch first; but if I don’t receive anything useful from this query, my only other forseeable option is to open it and search on the switch and/or circuit board references. At this point, I will settle for a link to a non OEM source, but prefer OEM. A link to a schematic would also be very useful. Thanks in advance for any information available.
