wiring small cables to big connectors?
(1/3) > >>

A couple of days ago posted about the below paradox. How to wire from a small PCB which lends itself to JST SH connectors with 28AWG wires to "big" pushbuttons that have spade connectors that require much larger AWG wires in order to be able to crimp.

There was no interest and somebody apparently cares  enough to delete the post. Here's a photo to illustrate the point.

In any case, current best solution doesn't involve wires but Capacitive Touch and 1206 SMD LEDs mounted on the reverse side of the board. The design files for the MCP product can be downloaded which is very kind of them and there's a microcontroller with capacity to spare so why not?

Still interested to know how to deal with the wiring thing...
MarkF:
Can you just solder the wires to the switch...
Don't bother with a spade connector.  Some of the spade terminals I've seen have holes.
Solder and heatshrink for strain relief.

foldback the wire and use the proper crimpers not the crappy die ones that are built into wire strippers.

Nice to know. Thanks for posting and the answer.

If yachtsmen bend their wires before crimping then it must be reliable.  Great tip, thanks. Think for 28AWG might have to bend more than once...

Love to solder! Check out this recent masterpiece: RJ11 via 28AWG to 24 AWG rigid wire (for power supply hook clips) and to 100ohm resistor (to keep the CANbus happy). I have a friend who fixes the holes in the pockets of his jeans with hot glue. Says it lasts them out. However somebody told me soldered connections weren't very pro so am trying to move away from it.
