1. A hearing aid;
- comprising;
amplifying means including an amplifier for boosting an incoming signal;
a power source operatively electrically connected to said amplifier; and
switching means for automatically controlling the electrical connection between said amplifier and said power source by automatically providing the electrical connection upon attachment of the hearing aid to the user and by automatically breaking the electrical connection when the hearing aid is detached from the user, said switching means including a switch responsive to a change of temperature and being arranged on the hearing aid at a location which is subjected to the change of temperature, said switch being a temperature-sensitive switch in heat-conducting connection with the skin of the user at said location when the hearing aid is mounted to the user.

Abstract
A hearing aid includes an electronic amplifier, an electric power source and a switch for automatically breaking or making the connection between the amplifier and the power source depending on whether the hearing aid is in use or out of use. The switch is provided in such a manner so as to be responsive to switching criterion defined by a change of state such as change in temperature, moisture etc. The switch is disposed at a wall surface which is subjected to the change of state.

11. A hearing aid;
- comprising;
amplifying means including an amplifier for boosting an incoming signal; a power source operatively electrically connected to said amplifier; and switching means for automatically controlling the electrical connection between said amplifier and said power source by automatically providing the electrical connection upon attachment of the hearing aid to the user and by automatically breaking the electrical connection when the hearing aid is detached from the user, said switching means including a switch responsive to a change of state and being arranged on the hearing aid at a location which is subjected to the change of state wherein said switch includes a biosensor which is responsive to the change of state when inserting the hearing aid in the auditory meatus of the user.

12. A hearing aid;
- comprising;
amplifying means including an amplifier for boosting an incoming signal; a power source operatively electrically connected to said amplifier; and switching means including a switch which is responsive to a change of state which occurs without direct actuation and without direct contact of the switch, said switch being arranged on the hearing aid at a location which is subjected to the change of state wherein said change of state causes said switching means to automatically control the electrical connection between said amplifier and said power source by automatically providing the connection upon attachment of the hearing aid to the user and by automatically breaking the connection when the hearing aid is detached from the user, wherein the electrical connection is maintained, indepedent of the position of the user, whenever the hearing aid is mounted to the user. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A hearing aid;
- comprising;
amplifying means including an amplifier for boosting an incoming signal; a power source operatively electrically connected to said amplifier; and switching means including a switch which is responsive to a change of state which occurs without actuation of the switch through mechanical means, said switch being arranged on the hearing aid at a location which is subjected to the change of state wherein said change of state causes said switching means to automatically control the electrical connection between said amplifier and said power source by automatically providing the connection upon attachment of the hearing aid to the user and by automatically breaking the connection when the hearing aid is detached from the user, wherein the electrical connection is maintained, indepedent of the position of the user, whenever the hearing aid is mounted to the user.
