Good day everyone,

I am looking at sourcing all the components, however I am having difficulty trying to find the encoder RE111F-41B3-25F-15P and the SPST SF12011F-0202-20R-M-027, anyone have alternate numbers or online stores where these can be odered? preferably a store that has both to save on shipping and in North America. I see Rapid has both however I have to buy Qty 5 switches, and I only need one. Or Ray would you be kind enough to include these two components in my PCB order such as you do for the two IC's?

Edit: After more digging for the SPST it seems like I could use 612-FS57SPMT2B2M1QEH from Mouser. Also what is the switch used in the kit? it does not have the same shape as the SF12011 called up in the BOM according to the datasheets.

Hi,
The encoder (RE111F-41B3-25F-15P ) is compatible with many other parts that are "incremental encoders with push button", the EC11E15244G1 and EC11E15244B2 are compatible, although they are a bit shorter than the original (around 0.7mm shorter approx.)

For the momentary footswitch (SPST SF12011F-0202-20R-M-027), you can use any "spst footswitch non-latching" somehing like those are always compatible:

If you have problems sourcing the parts, send me an email before placing the order.

what can i use instead of 2n5089 semiconductors?

2n5089 are simple and basic NPN transistors, you can use any reasonable part as a substitute like a 2N2222, 2n3904, etc.

I'm confused, SF12011F-0202-20R-M-027 at Rapid is a DPDT, not a SPST.

Yes, it is dual, but you can use just one of the "channels" and leave the other one unconnected.

Any momentary not locking footswitch will work

I get only using one part of the DP; it's the DT that's confusing me! In any case, with a SPST should it default to open or closed?

Edit: I figured the first part out with some Googling! Still not sure about whether the momentary action should open or close the circuit.

The switch should be open by default and closed when you push it.
You can really use any and then change the software but I am sure that it is simpler to stick to the original "Open by Default and closed when Stomped"
