According to one embodiment, a casing of a hazard detector includes a body portion and a button portion. The button portion is coupled with the body portion via a plurality of arms. The arms allow the button portion to be axially movable relative to the body portion and also couple the button portion with the body portion so that tabs that extend radially outward from the button portion are positioned under and contact an inwardly facing surface of the body portion. The arms bias the button portion axially outward relative to the body portion so as maintain contact between the tabs and the inwardly facing surface. In this configuration, when the button portion is pressed at a position off-axis from a central axis of the button portion, the button portion pivots about one or more contact points between one or more tabs and the inwardly facing surface.
