Two Toggle / One Duplex (3-2td) - These switch plates take up three spaces (gangs) and feature room for two Toggle switches and one Duplex (a pair of electrical outlets). This configuration is most commonly found in kitchens and bathrooms.
Most of these switch plates can be turned over (so the Duplex is on either the left or the right) without affecting the design. Be sure to look at the design on the product page to make sure. All of these styles have a Two Toggle / One Duplex switchplate available even if it is not shown in the picture below.
