Rotary Switch Availability

Many of my "moog" modules need Alpha (Taiwan) SR2511 series rotary switches. My preferred supplier for these has been even though they have a minimum order value. However they now appear to be out of stock with long lead times.
Mouser does stock compatible switches with round shafts. Round shafts are fine, just don't use "D shaft" switches with these modules or the knob won't align with the panel graphics. However all of the Mouser stock appears to be the "19R" shaft height variant, which will leave the knob very high above the panel which looks ugly.

I have located the following alternate suppliers, I have no connection to either of these:
- in the EU: has some stock of the Alpha parts (e.g. part number 12679 for 4P3W). They won't ship outside the EU, and note that the UK is no longer in the EU!
- in the UK: has compatible switches, part numbers 483323 for 4P3W (904C), 483320 for 1P12W (901A), 483321 for 2P6W (901B). These switches are "open" and don't have dust covers. If you only want one or two, it may be cheaper to purchase via their ebay shop.
 - elsewhere: if ordering PCBs from me, please ask about any switches you need. I can supply those from Switch Electronics "at cost", saving you any additional shipping costs.
