Question Wall light switch occasionally buzzes when used like wires are touching

Wall light switch occasionally buzzes when used like wires are touching. Should I open, examine and rewire? Would it help to post a photo of what it looks like inside? This is from a home built in 1966.

Check the connections. If back stabs move to the screws. If wires are on the screws be sure the screws are tight. If buzzing continues replace the switch.

"If back stabs move to the screws." ?

What Ray said. ................................

Use the screw terminals, not the backstabs.

Backstab -- Connection made by inserting the wire end into a hole in back and the wire stays in place without the need to tighten a screw or something. The wire will rotate easily within the hole. While these connections meet most codes, numerous complaints about loose connections have been observed over the years.

If the wire is inserted into a hole in back but you must tighten a screw somewhere to get the wire to stay in place, then the connection is better than a backstab and just as good as a screw terminal. Here the wire will not rotate in the hole if the applicable screw is tightened adequately.

Question Safety gloves instead of turning off the juice?

I don't know what switch / fuse turns off the juice to this room. Are there special (rubber?) gloves that could protect me as I tighten the screws without turning off the juice to this room? If not, is it safe to just try the fuses one at a time until the right room loses power? Should I worry about shutting off something important that won't be rectified simply by turning the juice back on, like cutting power to the boiler?

No such critter. It is either a breaker or a fuse. You need to turn the light on then turn off each 15 and 20 amp single pole breaker one at a time, off then back on if it doesn't kill the light. You can have a helper watch the light and use cell phones to communicate.

When you get this repair done you need to do that for every light and receptacle in the house and make a chart for your breaker box.

Question How do I tell the 15 and 20 amp single pole breakers from the others?

They have 15 or 20 on the handle and usually half the width of a two pole breaker. If in doubt if it is single pole and it is 15 or 20 try it.
