Kcs low power electrical push push switch by KidCrazy

Last crawled date: 3 years ago

This low power electrical switch is part of a reading lamp that I'm designing.
My design goals are:
no vitamins (i.e. completely printable except cables/electrics/electronics)
easy printing (avoiding excessive overhangs, etc.)
easy assembly
I wanted to make an electrical switch with push push mechanism, similar to the ones that are known from ball pens, but completely printable. This is the result of several weeks of design, trial, error and redesign.
The main idea is to have two cable ends connected and separated inside the mechanism, so it will propably only be save for real low power applications (like powering a LED).
The mechanism is complete except the part that connects the cables.
Update 2013-05-02:
Yesterday, I tested if the switch will still work after longer activation time. I set it to "on" (springs in compressed state) and let it in this position over night. Unfortunately, the big spring seems to have permanently deformed over this time and can't get back to full decompression, so the switch is stuck :(
Seems I will have another try at this one... propably more space and a longer spring will do, but I want to check other options first.
