Debbi,
One last note from me. Are you familiar with ESDS / ESD or otherwise an "Electro-Static-Discharge Sensitive" or "Electrostatic Sensitive Device"?
Especially in the winter time with drier air, it is easy to build up a static charge. I am sure that you have been zapped by this at one time or another, especially after walking across a carpeted floor. But, even walking across a linoleum floor can build up a static charge that can wipe out many electronic devices. Some may say that I am being over-cautious, but my personal advice is to play it safe with all electronic components. For the handling of your new switches, try to avoid all static buildup. Simplest way is to open the package the switch comes in atop your kitchen stove. Allow the package to sit on the stove for a few seconds and then place your hands on the metal frame of the stove prior to opening the package to bleed off any excess static charge. Then don't walk across a carpeted floor during or prior to handling the switch or any other component. That should help protect your electronic devices and components.
If you find you are "ZAPPING" door knobs frequently, then by all means, stay clear of all electronic devices until you discharge your static charge!
Please don't be overly fearful of this notion, just try to understand that if you are really "charged up", don't go handling your electronics without a little forethought.
