Abstract

An electronic key having the following features. The electronic key has a key housing and a switch housing in the key housing. The switch housing has an inherently rigid frame having at least one first breakout, and a flexibly deformable membrane which is arranged on the frame in order to close the at least one breakout and to forward a force having effect from the outside on the membrane in the region of the breakout to an electrical switch element arranged within the frame. An electronic key having the required amount of stiffness is thus created, in which sensitive electronic components located therein are also protected from environmental influences. If the deformable membrane is not only used for button-related functions, but also for forming an ejection section for an emergency key or as a rattle protection for the emergency key, a multifunctional switch housing can thus be created simply.
