发明名称 Hearing Apparatus with a Linear Switch
摘要 A hearing apparatus allowing a user to reliably switch the apparatus on and/or off includes a battery compartment for a battery and an actuation element disposed at the battery compartment for switching the apparatus on and/or off. A contact element has a contact point and taps an electric potential on the battery with the contact point when the actuation element is in a first position. The actuation element, in a second position linearly displaced from the first position, lifts the contact element at a lifting section of the contact element being different from the contact point, to remove the contact point of the contact element from the battery. Thus, the contact point of the contact element only contacts the battery and no additional material, preventing materials from being scratched and an electric circuit from being interrupted and ensures that an even, grippable surface of the actuation element is always available.
