So My MS-51 has a Broken Housing and My MS-5 has broken Pigtail Wires. Just today some thing hit me. “Would it be possible to swap the Working Button from the MS-51 with the Broken Button on the MS-5 in order to fix the MS-5?”
So I tried that. I removed the Washer holding in the Buttons and swapped the Buttons. Result? I now have a Working Pyr-A-Larm MS-5. Although it is technically now an MS-51.
What are your thoughts on this Experiment?
