I'm going to assume that the switch that's getting warm is the dimmer. Even when a dimmer is working correctly it gets warm and that's just the electronic parts of it. The face of a dimmer is actually a heat sink to help remove excess heat.
If you swap out the dimmer you will likely find your problem is resolved. Remember to de-energize the circuit by turning off the breaker before working on it.
If in any doubt, consult a qualified electrician.

Be aware that a dimmer for lights does NOT work for fans (though it may sometimes appear to work, you can end up with noise, problems such as the light attached to the fan not working, the dimmer getting overheated, etc). So even though it might seem to work at first, you'll have problems, and it's against code to put the wrong kind of dimmer there. You can purchase a dimmer which is rated for ceiling fans at Home Depot or Lowes, but they are more expensive than light switch dimmers.
Of course, if there is a single on/off switch at the wall which controls the fan and its light, then you might be better off buying a remote control unit to install in the fan - it will allow you to dim the fan and light separately (and safely). Or purchase a new fan with a remote... ceiling fans are cheap enough now that if yours is old enough, it might be a nice time for an update.
An electric dimmer switch for lights can reduce the light output by adjusting the amount of electrical current flowing to the light bulb. By decreasing the current, the dimmer switch can lower the brightness of the light emitted.
Your question is a bit unclear and vague, but if you have a dimmer switch and you turn it all the way to its lowest setting then the switch should not fail because of that. If there is nothing wrong with your electrical system then using a device exactly how it was designed to be used then there is no reason why it would catch on fire.
The noise emanating from a dimmer switch is typically due to electronic components vibrating as the dimmer adjusts the electrical current flowing to the light. It could also be caused by loose wiring connections or the dimmer switch itself. If the noise is excessive or accompanied by sparking or burning smells, it may indicate a larger issue that requires professional attention.
This issue could be caused by a faulty low beam relay, a blown fuse, a bad headlight switch, or burnt-out low beam bulbs. Check these components to determine the root cause of the problem and replace or repair as needed.
A dimmer switch typically has two red wires to allow for multiple connection options. One red wire is usually connected to the power source, while the other red wire is connected to the light fixture. This setup enables the dimmer switch to control the flow of electricity between the power source and the light, allowing for adjustable brightness levels.
Yes, the dimmer switch could be at fault but, be sure the bulbs are okay before you spend anymore money.
could be the the headlight switch, dimmer switch, headlight relay, or a problem with the wiring
Could be a number of things, and you'll probably have to get a digital multimeter to trace the problem. It could be a problem with the headlight switch, the dimmer switch, the wiring, the lamp harness, or the fuse panel.
Replace your dimmer switch and this should fix your problem Or both bulbs could be bad
Headlight dimmer switch is defective
The dash illumination light (dimmer) switch could be in the off position.
Yes, it could.
Yes it could.

Bad dash light, or dimmer fuse. Or a bad dimmer switch itself
No, it is not safe to touch a dimmer switch when it feels hot. This could indicate an electrical issue that may pose a fire hazard. It is best to turn off the switch and have it inspected by a qualified electrician.
Bab bulbs? (they are double filamented) Bad dimmer switch? Bad low-beam relay?
