Abstract: A detachable component of a wearable medical device in accordance with an embodiment of the present technology includes a housing and a latch operably associated with the housing. The latch includes a cam having a first position at which the cam projects outwardly from the housing, a second position at which the cam is shifted inwardly relative to the first position, and a third position at which the cam is shifted inwardly relative to the second position. The cam is resiliently biased from the second position toward the first position. Fully actuating the cam moves the cam from the first position to the second position. The detachable component further includes a handle accessible from outside the housing. The handle is movable in an actuating direction to move the cam from the first or second position to the third position.
