I had real difficulty sourcing the part for this, I don’t think this is actually an Omron switch for the middle mouse button. The part I pulled from the Razer mouse is actually branded ‘TTC’. I ended up sourcing them from Aliexpress:
I'm trying to fix a Razer Naga Pro where the middle mouse button is double registering clicks and I stumbled across this guide. The switch appears to be very similar so I was hoping to be able to order a replacement based on the guide but I can't find anything from searching 'OMRON D2 Subminiature Micro Switch', and the switches that Andy Smith linked aren't right (I ordered some and they're too thin) so I'm somewhat out of ideas. This would be less of an issue if Razer even offered out-of-warranty repairs, but they consider peripherals to be 'irreparable'.
I think I managed to find them! If anyone else is looking for information on these switches, they appear to be the TTC switches here: http://www.ttcswitch.cn/product/72.html specifically the 5.6mm variant. I have ordered some from a website called Mouse Club and will update when they arrive.
As mentioned by the other comments, the correct replacement switch is the linked TTC switch, specifically the 5.6mm high variant. However, I didn't manage to find a viable seller for this type of switch.
In the end I purchased the 3.5mm variant (as linked by Andy Smith; it's available from different brands, I chose this one from HUANO). Of course this switch is about 2mm too short, so I made a little spacer from a 2mm plastic sheet (should also work with 3 layers of old credit card pieces), drilled two holes for the leads and installed the switch. The leads are just barely long enough to stick through the board with the spacer so they can be soldered in place. (photo)
Now my mouse works perfectly again, but I'm still baffled that I couldn't find the 5.6mm switch on Aliexpress.
@michael39629 I have been looking for the switch to use on this, and this is also the only option i have found. Do you by chance still have the spacer stl that you could maybe share? I wanted to print the spacer before the switch arrives. Worst case i can model it myself then, though.
