Abstract
An electrical product includes a housing with a movable cover and, at least one module receiving slot which 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 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.

An electrical device comprising:
- a housing defining an interior region bounded at least in part by a movable cover;
- at least first and second receiver slots defined on the housing adjacent to the cover;
- at least one proximity switch where the one switch is associated with one of a respective slot, or a respective conductor of the housing;
- and
- a latch element located adjacent to at least one of the slots or conductor and wherein the movable cover carries a selected region configured so that at least a portion of the region is located to cause a change of state of the switch when the cover is at a first position.
A product comprising:
- a housing with a movable cover and, at least one module receiving slot which can be closed by the cover wherein the housing carries control circuits, and a proximity switch is carried on an insertable module, wherein when a module is inserted into the slot, and the cover closed, an electrical signal can be coupled to the control circuits, and, 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.
