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.
