So I'm going through my house, replacing the switches and came across this switch that controls a fan in my bathroom. It looks like this may have been something the previous owner did, and did incorrectly.
If you notice, there is this strange coiled wire looped around the terminals. The wire itself appears to be stripped in the middle for the terminal connections and continues with the tip exposed. This looks bad and I think should be fixed.
In the bathroom, the light switch controls power to this switch, so the light switch must be on to use the fan. I assume that the wires from the light switch, go to the light, then to the fan. From the fan, I believe the hot splits off and goes to this switch and back. There is no ground in the box for this switch.
The problem itself is not that big of a deal for me, just an annoyance.
- Besides having the ends exposed, is using this coiled wire a hazard?
- Should there be a ground wire with the switch?
- Should it be replaced with standard 14 gauge wire?
- Any other concerns that may stand out based on what I described?
Probably the best thing I can do is to replace it and make the fan independent of the light. This just puts a lot of work on my end as I only want to update the switch, for now. I have other plans to get an electrician to add circuits to my house at some point, just not anytime soon.
I'm a little afraid to pull it out as I believe the wires will not stay in place/can bare any weight without dangling. Here is a different angle of the switch, you can see the majority of the box.
