An enclosure housing has a first wall defined as a molded polymeric construction, a first latch defined as a one-piece construction with the first wall, a second wall defined as a molded polymeric construction, and a second latch defined as a one-piece construction with the second wall. A circuit board is connected to the enclosure housing and includes a board member defined by a periphery. The periphery includes: (i) a first tab defined by a first inclined ramp surface and a first locking face that lies transverse to the first inclined ramp surface, wherein the first tab is engaged with the first latch; and, (ii) a second tab defined by a second inclined ramp surface and a second locking face that lies transverse to the second inclined ramp surface, wherein the second tab is engaged with the second latch.
