Abstract

A push button device (100) comprises a button head (10), a stationary housing (20), an inner casing (30) being movably arranged inside the stationary housing (20) between a first position (1) and a second position (2), when a pushing force is exerted to the button head (10), a compliant member (40), and an engagement element (50). The stationary housing (20) and the compliant member (40) are configured such that the engagement element (50) engages with the stationary housing (20) in the first position (1) and second position (2) of the inner casing (30) inside the stationary housing (20), and the compliant member (40) is deflected as a result of which the engagement element (50) disengages with the stationary housing (20) in an intermediate position (3) of the inner casing (30) inside the stationary housing (20).
