Claim:
A base for mounting on a DIN rail, the base comprising a body and a latch assembly; the body including an interior cavity for an electronic component, a surface extending between a DIN rail location and an actuation location, a retention member adjacent the DIN rail location, a first wall extending along said surface, and a first recess in said first wall; said latch assembly including a release member on the surface and extending along the wall, an actuator at said actuation location, a first attachment member adjacent the DIN rail location, and a first projection on a side of the release member adjacent the wall; and a latch member adjacent the DIN rail location, the latch member including a second attachment member engageable with said first attachment member to mount the latch member on the release member, and a latch engageable with a DIN rail; the release member having an assembly position away from the DIN rail location with said projection physically engaging the wall adjacent the recess to prevent movement of the release member along the surface and permit mounting of the latch member on the release member by engagement between said first and second attachment members; said latch assembly having an operative position where the release member is closer to the DIN rail location than when in the assembly position, the first projection is in said first recess, a portion of the latch member engages the retention member to secure the latch member on the base, and the latch assembly is movable toward and away from the DIN rail location to engage and disengage a DIN rail.
