If it is dimming the light, yes. A dimmer switch is nothing but a potentiometer, better explained as a variable resistor. It will lower the voltage going to the light bulb, but the excess energy must go someplace, and is released as heat. The lower the brightness, the warmer it will get (until it is turned all the way off).
There are newer dimmer switches that work in different manners, but I don't believe that is what you are referring to.
The "triac" in the dimmer, which is what dims the light, generates heat caused by the electricity flowing through it. The dimmer is made of a large piece of aluminum, which acts as a "heat sink", allowing for a better dissipation of the heat.
A light switch gets hot because the internal contacts have lost their tension against each other to make a proper contact. This loss of tension starts to create a higher than normal resistance within the switch. When the current flowing through the switched circuit travels through the switch this resistance is encountered and the result is heat being generated. With the operation of the switch from the on to off positions compounds the problem due to heating and cooling the contacts. About this time the circuits breaker will start tripping trying to protect the switches circuit. Over time this resistance increases and eventually enough heat will be generated through the switch contacts to burn the contacts completely. Change out any switch that you are not comfortable with, as it is cheap insurance for peace of mind.
Any resistive material with electric current passing through it will increase in temperature. However, if the switch is working correctly it should not get hot.
A light switch should never get hot and if it does it should be removed as a fire risk and replaced with a new switch.
Dimmer switches go bad, more often than regular switches.
no
A dimmer switch is very helpful as if you attach one to your light switch you can control your light intensity, the Lutron Dimmer is a brand dimmer switches that provide high quality performance.
No, the dimmer switch needs its own individual circuit power supply to feed the fixtures connected to it. The black of the second dimmer switch can not be connected to the red wire of the first dimmer switch. Now if you are talking about using a common "hot" to feed two dimmer switches then this can be done. The neutrals will be common also. So what you should have is two black wires connected together with the incoming "hot". Two neutrals connected together with the incoming white. The red from each dimmer is then connected to its own individual fixture load.
One 3-way dimmer switch, one regular 3-way switch and one 4-way switch. The 4-way is wired between the two pairs of travelers from the other two switches. The common on the dimmer is tied to either the light or to the branch hot and the common on the other 3-way is tied to whichever is left (hot or the light).
A person could buy discounted dimmer switches from Discount Dimmers. Another option is from Amazon. These discounted dimmer switches prices at $10 and up.

Answer Actually dimmer switches extend the life of a light bulb, especially if you dim them often.
no

I think you may be talking about the dashboard dimmer switches.
Down by where the dimmer switches were once located.
Older types of dimmer switches used a small transformer in them for a control power supply. Change this unit out for a new one as the technology has come a long way in the past few years.
