## Background
BACKGROUND
Programmable light switches used in home automation systems often need to be installed permanently in the wall in the place of an existing light switch. Permanent installation of a programmable light switch may require an electrician, as the existing light switch may need to be disconnected from building's wiring, and the programmable light switch wired into the wall. This may make replacing existing light switches with programmable light switches as part of a home automation system costly and time consuming.
Programmable light switches may also function as remotes, without being connected directly to a building's wiring system in place of the existing light switch. However, in this case the existing light switch may still control the flow of electricity to home automation equipped lighting fixtures. If the existing light switch is switched off, the remote programmable light switch may no longer be able to control the home automation equipped lighting fixture, as the light switch will cut off electricity to the light fixture, and to any home automation hardware within the light fixture.

DETAILED DESCRIPTION
An interchangeable back system may allow a programmable switch, for example, a programmable light switch, to fit over an existing light switch, thereby preventing the existing light switch from being turned off accidentally, and eliminating the need for an electrician to hardwire the programmable light switch. The interchangeable back system may allow the programmable light switch to be a remote control that fits comfortably in a user's hand. The interchangeable backs for the programmable light switch may be of various shapes and depths, allowing the backs to fit over various existing light switch types, such as, for example, paddle or toggle light switches. A slimmer interchangeable back may cover the back of the programmable light switch and make the programmable light switch more comfortable to hold in a hand. The interchangeable backs may include batteries to power the programmable light switch.
The interchangeable backs may be installed to act as the back of a programmable light switch. Any suitable attachment system may be used to hold one of the interchangeable backs on the back of the programmable light switch, including, for example, friction tabs, slotted tabs, friction fitting, and any other form of releasable attachment. Friction tabs may be tabs that create friction and may be released by pressing near the tab locations. Slotted tabs may be tabs that insert into corresponding slots, and are releasable by pressing near the slot location. The interchangeable backs may be easily installable on and removable from the programmable light switch, which may allow for appropriate backs to be installed on the programmable light switch depending on the intended use for the programmable light switch.
One of the interchangeable backs may include an opening which may fit over a traditional toggle light switch. The interchangeable back may have sufficient depth so that when the back is placed over a toggle light switch, the toggle light switch may be contained entirely within the interchangeable back, without causing the light switch to change to the off position. This may prevent the toggle light switch from being turned off while the programmable light switch with interchangeable back is installed over the toggle light switch, allowing the programmable light switch to control the functioning of any home automation equipped light bulb or light fixture connected to the toggle light switch.
One of the interchangeable backs may include an opening which may fit over a decorative, or paddle, light switch. The interchangeable back may have sufficient depth that when the back is placed over such a paddle light switch, the paddle light switch may be contained entirely within the interchangeable back or within a cavity on the back of the interchangeable back, without causing the paddle switch to change to the off position. As with the toggle light switch, this may allow the programmable light switch control over any home automation equipped light bulb or light fixture attached to the paddle light switch.
The interchangeable backs may be attached over existing light switches in any suitable manner, including, for example, adhesive strips attached to the interchangeable backs. The adhesive strips may be positioned to allow the programmable light switch with interchangeable back to attach over the appropriate existing light switch for the interchangeable back being used by adhering to, for example, the cover plate covering the switch. The interchangeable backs may be removable after being attached, allowing the existing switch to be exposed. In some implementations, the back plate of the interchangeable back may be removable from the rest of the interchangeable back and programmable light switch, and may be able to stay in place, for example, adhered to the light switch, after the programmable light switch and rest of the interchangeable back are removed.
One of the interchangeable backs may allow the programmable light switch to be held comfortably in a user's hand. For example, the interchangeable back may be shaped and contoured to better fit into a human hand, including having less depth than the interchangeable backs intended for attachment over existing light switches. The interchangeable back may allow the programmable light switch to be used as a hand held remote.
