What type of space are you wiring?
For RVs and mobile homes, self-contained switches that include a cover plate and compact footprint simplify installation and reduce the risk of wiring mismatches. In small cabins or apartments, a standard self-contained switch can streamline upgrades without an entire panel replacement.
