Claim of US Patent No. 9,967,995

1. An electronics module comprising:a housing including a rear face comprising a recess adapted to receive an associated mounting rail, said recess comprising first and second opposite edges;
a latch assembly connected to said housing and adapted for selectively releasably securing said housing an associated mounting rail located in said recess, said latch assembly comprising:
a first latch portion movably connected to said housing and comprising a locking tab adapted to capture a first associated DIN rail flange in said recess;
a second latch portion movably connected to said housing adjacent said first latch portion and comprising a second locking tab adapted to capture a second associated DIN rail flange in said recess;
said first and second latch portions linearly movable relative to each other to and between: (i) a latched configuration where said first and second latch portions are located in respective latched positions in which said first and second locking tabs project respectively beyond said first and second opposite edges of said recess and partially obstruct said recess; and (ii) an unlatched configuration where said first and second latch portions are located in respective unlatched positions in which said first and second locking tabs are spaced farther apart from each other as compared to the latched configuration;
first and second springs, wherein said first spring exerts a biasing force on said first latch portion that urges both said first and second latch portions in a first direction relative to said housing when said first and second latch portions are located in said unlatched configuration, and wherein said second spring exerts a biasing force that urges said first latch portion in said first direction and urges said second latch portion in a second direction that is opposite said first direction.
