I have a number of different switches, all with solder lugs more or less similar to this:
I have soldered some stranded wire to it, using a method I found in a video where the stranded wire is stripped, the exposed strands twisted and soldered together, then put through the hole in the lug and soldered to the lug. The electrical connection works great, but I worry about the mechanical stress on the connection. Here is a picture of the soldering job itself:
I can easily bend the wire 90 degrees from the contact point if I wanted to, which doesn't give me much confidence in the mechanical strength of the connection. Is this a job that shrink wrap/electrical tape could fix? Or should I be soldering this differently?
