Abstract: An electrical product includes a housing with a movable cover and at least one module receiving slot that can be closed by the cover. The housing carries control circuits. A proximity switch is carried on the module. When the module is inserted into the slot and the cover is closed, an electrical signal can be coupled to the control circuits in the product. When the cover is opened, a different signal can be coupled to the control circuits in the product. A first latch element can be carried on the housing, adjacent to the slot, to retain the cover in the closed state. A second latch element releasibly engages the first latch element when the cover is closed.
