The STOP and RESET buttons are from a Documation card reader.[1] They're not guarded. They just come from a standard kit of buttons and lamps where you could assemble the components and dividers into a control panel. That style of illuminated push button was once popular and is still available.[2] NASA Mission Control consoles had lots of them.
