Studio Technologies has created a video which provides details on how to repair the pushbutton switches that are used in the StudioComm desktop control consoles and Model 400-Series fiber transport units. Typically only a cleaning is required to return them to full working order.
Cleaning typically only requires a small flathead screwdriver or a thin plastic pry tool, a pencil eraser, a cotton swab, and a can of contact cleaner. Using the screwdriver or pry tool, gently pop off the cap of the pushbutton switch to reveal the stamped metallic “dome.” Remove the dome, then clean it with the contact cleaner. Using the swab and contact cleaner, clean the two metallic contacts within the base of the pushbutton switch. Alternately, the two contacts within the base of the switch can be cleaned with the pencil eraser. If either or both of the contacts in the base are bent down, use the flathead screwdriver and gently pry them upwards until they are horizontal. Re-install the metallic dome and button cap and the process is complete.
In the rare event that a complete pushbutton switch or internal switch component needs to be replaced, please refer to the Replacement Parts List document, available on the Technical Support page.
