Ganging a plurality of wall mounted electric devices

A method for ganging at least a pair of control devices each adapted to control at least one function of at least one associated load, the method comprising the steps of:

• inserting a plurality of tabs that traversely extend from a first side surface of a vertical wall of an alignment plate into a plurality of recesses formed on a side surface of a housing assembly of a first control device;
• inserting a plurality of tabs that traversely extend from a second side surface of the vertical wall of the alignment plate into a plurality of recesses formed on a side surface of a housing assembly of a second control device;
• wherein each recess comprises an inner side wall that tapers inwardly from the side surface of the respective control device, wherein each tab comprises an outer side wall that tapers inwardly from the respective side surface of the vertical wall of the alignment plate;
• and
• applying pressure to the pair of control devices toward each other such that the tapered outer side walls of the tabs on the alignment plate form a friction fit with the tapered inner side walls of the respective recesses of the pair of control devices to removably secure the pair of control devices to the alignment plate.
