Use space-saving stacked light switches to add 2 or 3 devices in the same size electrical box.
Combining Two Switches into 1 Gang:
Put two switches into a single gang of your electrical box with this stacked Decora Rocker switch from Leviton.
Each individual switch rocks side-to-side to control the lighting and fits perfecting into standard rocker plate openings.
Here is another style of dual rocker switch from Leviton, which has smaller horizontally flipped switches that fit a standard rocker opening as well.
Fit 3 Switches into a 1 Gang Plate:
Another combo switch with 3 switches in 1 gang is Pass & Seymour's RCD113 combo switch.
Two switches sit side by side on the top half, and a larger switch occupies the bottom half of this single device with three switches.
All switches flip up and down.
This switch also fits rocker wall plate openings.
