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.
Claims19
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 movable cover;
- a first proximity switch that indicates when the movable cover is in a closed position;
- a latch element located adjacent to at least one of the first and second receiver slots, wherein the movable cover carries a selected region configured to cause a change of state of the first proximity switch when the movable cover is in the closed position;
- and
- a second proximity switch;
- wherein a first module is located in the first receiver slot and a second module is located in the second receiver slot, and wherein movement of the movable cover communicates a change of state of the first proximity switch and the second proximity switch to control circuits carried by the housing.
A product comprising:
- a housing with a movable cover and a first module receiving slot that is closed by the movable cover;
- control circuits carried by the housing;
- a proximity switch that is carried on an insertable module, wherein, when the insertable module is inserted into the first module receiving slot, and when the movable cover is in a closed state, the proximity switch communicates a first electrical signal to the control circuits indicating the movable cover is in the closed state, and, when the movable cover is in an opened state, the proximity switch communicates a second electrical signal to the control circuits indicating that the movable cover is in the opened state;
- a first latch element carried on the housing, adjacent to the first module receiving slot to retain the movable cover in the closed state;
- and
- a second latch element that releasibly engages the first latch element when the movable cover is in the closed state.
