Some time it’s the time to make a decision. The rocker switches in the drawer seem to be self-made by M. Martenot and have degraded seriously over the years. Poor contact, some are sluggish, others have too much slackness. For the use of the instrument it seems much more important that the switches operate correctly without causing additional audio noise due to poor contacts than having genuine switches under the hood.

Here’s what I’m planning to use:

The Marquardt rocker switches will be mounted in an additional sheet of metal which will also keep the axles for the original transparent levers in place.
