This is some big Emergency Button. I use it with my HouseAutomation to control things and stuff.
As button itself i use a black Cherry MX switch that i had laying around. Works nice :)
When it was printed i thought a lower height would be great, so i added a 15mm/piece version. The version in the video is 30mm/piece.
What you need to do it like me:
- all three printed parts
- Cherry MX switch of your choice (i got mine from Conrad Germany
- NRF24L01+ Radio
- some cables
- some M3 Screws (M3x30+ should do fine)
You can read more about that stuff here:
I stole the idea for fixing the knob to the switch from ohagel. Thanks buddy, mine creation did not work as expected ;)
I changed the plate thickness of the top part from 1mm to 1.5mm, that should make the Cherry Switch fit much better.
I think using one cherry switch is great. But using 4 cherry switches is even four times greater. So i added a top and a knob that can handle 4 cherry switches. I made one, and it feels very good. Sadly yellow is empty, so mine is gray.
Added CAD files. Please be nice, i am not that good at it.
Printed on my Ultimaker2 and sliced with Simplify3D.
Print "Knopf" with support, but remove possible support on the part that slides on the cherry switch.
Mine version is printed pretty fast and not best quality, since it should be a prototyp. But works, so who cares ¯\(ツ)/¯
Push the big red knob onto the Cherry switch. Maybe you need some sharp knive and remove the "elefant foot". It should fit tight.
Cable it up like a mess, isulate the electronics stuff and throw inside the button. Then close and screw together.
