The housing includes an internal void defined by two or more walls. A plurality of receiving terminals, including corresponding conductors, are located within the void and are configured to interface with a modular electrical component when it is inserted. The housing also includes wire ports configured to connect to a building's electrical wiring, thereby providing an electrical connection between the building wiring and the conductors of the receiving terminals. This configuration allows the housing to be permanently installed and wired, while a functional electrical component, such as a physical switch, a power outlet, or an intelligent networked controller, can be removably inserted into the housing's void at a later time without direct manipulation of the building wiring. The receiving terminals can include isolation channels, and at least one channel may be keyed to ensure proper orientation of the inserted component. ## Claims ### Claim 1 A modular electrical housing, comprising: ### Claim 2 (depends on 1) The modular electrical housing of claim 1, wherein each of the plurality of receiving terminals comprises an isolation channel, and wherein each of the corresponding conductors is located within a respective isolation channel. ### Claim 3 (depends on 2) The modular electrical housing of claim 2, wherein at least one isolation channel is a keyed isolation channel having a shape different from other isolation channels in the internal void to ensure a pre-specified orientation of the modular electrical component when inserted into the modular electrical housing. ### Claim 4 (depends on 1) The modular electrical housing of claim 1, further comprising a locking mechanism configured to secure the modular electrical component within the internal void. ### Claim 5 (depends on 1) The modular electrical housing of claim 1, wherein the internal void is partitioned into a plurality of distinct bays by one or more internal dividing walls, and wherein each of the plurality of distinct bays includes a corresponding set of the plurality of receiving terminals. ### Claim 6 A modular electrical component for insertion into a modular electrical housing, comprising: a front face comprising a user interface;
