DEC Multia Power Switch Coupling
This is a coupling for the linkage between the front panel power button and the power supply power switch on a DEC Multia workstation. The original coupling is rubber or a soft plastic that fails with age, requiring the case to be opened to turn the computer on and off.
The square recess in this part fits somewhat loosely on the power switch post, but stays in place. The metal rod that links from the power switch to the front panel button is a press fit into the round hole. When everything is seated tight, the power button is flush with the front panel of the Multia when powered off.
