Hey, y’all! Introducing my custom Switch Breaker!

This is the KIT version.
Some things to note about the KIT:
-You will need to solder
-a hex kit is needed. 1.5mm and 2mm hex is required
-Liberation is highly recommended, I use - "Super Lube-21030 Synthetic Multi-Purpose Grease"
-Will take about 20-30 minutes to complete

This switch breaker will break in your switches for you. I personally designed these to break in my Novel Key Creams and it's been working great!

This mechanism is printed in PETG so it is stronger than PLA, whilst having more heat resistance (Won’t melt if you leave it in your car during summer). It’s also UV resistant so if it’s loud for you, you can leave it outside without concern!

You can also vary the RPM by adjusting the potentiometer screw on the buck converter! Adjusting within 5v-7v is supported, outside of this range is not supported by a micro USB. I'm unsure of the RPM range, but it should be between 100 to 150 rpm in addition to the two actuations per rotation design.

It’s powered by a micro USB cord WHICH IS NOT SUPPLIED! This is connected to a buck converter. Ensure your USB cable is supplying the proper 5V and 2A, if not, you may have issues.

If you are using an alternative way to power the buck converter, MAKE SURE YOUR DC 2V-24V.

I AM NOT RESPONSIBLE FOR BROKEN SWITCHES!!! USE AT YOUR OWN RISK! However, I can say I’ve used these for 40,000 actuation without issue. Your mileage may vary. I just did some final testing and I was able to get a total of 3 days of continuous usage in with no issue at all. That's 864000 ACUTUATIONS!!! Assuming 100 rpm and 200 actuations per minute.

Here is a sample spreadsheet to calculator your actuations!
