Why would a wall switch be warm to the touch?

electrical stuff naturally will be warm because it is resistive but an overloaded switch will also get hot and that is not good 2 reasons 1) To much load on the circuit 2) The switch is old and needs replacing. Both of the above needs an expert to fix them If it's a dimmer switch, it can get something like 180 degrees hotter than ambient air temperature if it's a 600 watt dimmer. please refine your question is this a dimmer switch? if so its natural for a dimmer switch to do this because its actually adding resistance to the circuit to dim the lights... resistance in the dimmer switch causes the heat If this is a single pole light switch replace the switch or check for an overloaded switch Absoulutely have a look at your connections inside the switch box. Dimmer or not. If it is noticibly warm to the touch, you probably have a loose connection creating the heat and preparing you for more heat when the fire starts. since you asked the question I assume you would need someone to identify the heat source for you and fix it. The above answers do not hold wire unless you have a large wattage dimmer, even then it it needs to be looked at. overloaded circuits are protected by the breaker and the wire should be hot all the way to the load. switched don't overheat when they get old, only with loose connections. Seek help!

Too many things plugged into that outlet. Simple check is to divide total watts by the house voltage to find amps. For instance lets say that you have a toaster oven than requires 1100 watts, and a coffee maker with 500 watts plugged into the same outlet. Take the total watts (1600) divided by voltage (110) and that equals about 14.45 amps. If your circuit breaker for that outlet is rated at 15 amps, you risk the wires being heated up enough to cause a fire. Normally, several outlets share one circuit breaker, so that reduces the amount of 'load' you can put on any one single outlet.

The two most likely possibilities: It's failing, or it's being over loaded.

increase the amperage of the switch. if it is a 15 amp switch, change it to a 20 amp switch. you also can reduce the load on the switch, which will relieve the heating. in either case, do it NOW, that switch can start a fire at any time. be prepared to pay 5 to7.00 for a 20 amp switch.

It depends on whether you are talking fahrenheit or celsius. Fahrenheit would be warm to the touch. Celsius would burn your fingers.

someplace warm like, your insulation in your wall if it found a way, just cjeck in all warm areas.

Water which is just warm to the touch. Not warm enough to scald.

This past weekend I painted the interior brick wall in my bedroom. In the winter, the room is cool and never gets above 64. I live in Michigan and it got into the mid-teens overnight. When I went to pull off the blue edging tape where the wall meets the carpet, it pulled off the new paint! The wall was cold to the touch. I had primed the wall with Kilz and had painted using Glidden. The paint can said that the temperature should be 50 or above. I do not know what the temperature of the brick wall was when I painted. I currently have a space heater in the room and the door is closed. My thought is that the warm room will cure the paint that is on the wall and warm up the bricks. Time will tell, it is 14 degrees outside. If I had to do it again, I would wait until it warmed up outdoors. If I was forced to paint (?) I would warm the brick up first and keep it warm until the paint had cured.

Most electrical switches even if designed and built correctly have a small amount of resistance to current flow.The upshot of this is that power is lost in the switch when current flows, ( from Ohm's Law: W=I x I x R, where W = watts, I = Amps , R = Ohms) In conclusion, where current flows through a resistance ( in this case the switch ) power is lost in the form of heat. Generally a 20A switch would be 'warm' to the touch, if it is 'hot' then this may indicate that the switch has a fault, for example a loose joint/connection or deteriorated contacts.

because you have a warm temperature in your skin and when you touch it, it is cold.

The infected area becomes warm, reddened, and tender to the touch when there's infection at a site.

If you do not touch it, by radiation. If you touch it then by radiation and conduction.

Add equal quantities of rice and water, then switch it on. If it has a button which switches from cook to warm then it should switch itself to warm when it is finished. It can be left at warm for an hour or so depending on your cooker.

The best temperature to paint a wall is warm ok bye

Red, swollen, warm to the touch, tender.

Depends on what you call warm! But around mid May the mercury will begin to touch 70s.

User Avatar

then that would mean that you are over powering the outlet so it might explode soon and you might not any more electricity in the house

Depends... Has he been in light?

spirits usly dont cause harm to others but when there just passing through its usly cold and if they want to protect you or get your attention it can be warm hope it helps :)

warm water because the cold water will freeze the cell wall.

The rings could be bad and may needto be replaced. Try getting a compression test to see if they are bad or not. The reason it would run better warm is because the piston and rings expand when warm and this would cause a better seal between the cylinder and the cylinder wall.

Yes. In most eco-friendly homes they would have a thing like a "soil/dirt/mud wall" and it would warm the house all winter.

If it's an exterior wall it could use more insulation in it to block the sun's heat or in winter the cold. Or if it's near a kitchen or bathroom it could be the heat from the hot water pipe. Also wall receptacles do not get hot unless over loaded. How long has it been hot? I noticed it 2 days ago. It's in my son's bedroom, right next to where he sleeps, of all places. So I'm concerned. It's about a 2' x 2' area and it is an exterior wall. There are no outlet's on that wall at all.

When you replace wall insulation, you are first going to have to tear down the entire walls. You will have to place a layer of foam and fiber to keep the wall warm.

from warm to cool, warmth is energy, coolness is the absence of energy.
