Abstract

A hearing instrument has a battery compartment switch which causes the hearing instrument to switch on/off. An electrical contact to the battery is established and interrupted by the battery compartment switch when the battery compartment is closed and opened. An on/off contour in the area of the battery compartment and a correspondingly shaped battery contact device are provided, the configurations are tailored, so that the lift-off area for lifting the battery contact device away from the battery and the contact area of the battery contact device are separated from one another. The battery contact device has a lift-off area and a contact area. Both areas are configured separately to reduce the wear on the on/off contour and to secure electrical contacting of the battery. This enables a lift-off area with a large surface, through which the mechanical pressure on the on/off contour is distributed and is thus reduced.

Claims6

Dependent claims

A battery compartment switch for a hearing instrument, the battery compartment switch comprising:

a housing;
a battery compartment able to be moved into and out of said housing;
a battery contact device with a contact area for electrical contacting of a battery inserted into said battery compartment, wherein said battery contact device disposed on one of said housing or said battery compartment, said battery contact device further having a lift-off area, said lift-off area and said contact area disposed separately from one another;
an on/off contour disposed on the other of said housing or said battery compartment not having said battery contact device, for interrupting an electrical contact between said battery contact device and the battery, wherein said on/off contour, when said battery compartment is moved out, interacts with said lift-off area of said battery contact device;
and
said on/off contour and said battery contact device embodied such that, when said battery compartment is moved out, said battery contact device is lifted such that no mutual friction occurs between said contact area and said on/off contour.
