Tevo Black Widow Microswitch clamp

thingiverse

I designed a clamp to hold a sub-mini micro switch with lever as a replacement for the original proximity sensor on the Z axis, which had failed. I managed to obtain this switch from a local electronics supplier and, although it may not be unique, it can be found at any electronics stockist. For reference, I've included a link to the one I purchased. To create the clamp, I simply removed the dead proximity switch and identified the two wires that transmitted the signal to the controller. I then soldered them to the micro switch. The process was straightforward. Next, I glued the switch to the printed part and adjusted its position by clamping it to the extruded aluminum frame of the printer. This allowed me to fine-tune the switch's sensitivity until it was perfectly aligned with the print bed.
