New home normal-voltage and low-voltage systems can offer many amenities.
Decora switches and dimmer switches are attractive and easy for older people to use. Switches can be three-way or four-way for control of a light from multiple locations. An example would be a switch at the top and the bottom of a stairway.
The dimmer switch looks almost the same as a normal switch with the sliding-bar dimmer control on the right edge of the switch. The dimmer has a dividend of being back-lite for easy access in the dark.
Multiple switches are pictured for control of all outside lights and outside switchable power plugs from a single location. In this case, control of many of the outdoor lights is also available in other locations by use of three-way and four-way switches.
