Abstract
Described is state switch for a hearing aid that provides an input to the hearing aid's processing circuitry indicating that battery power has been disconnected by a power switch. The state switch and power switch are configured to operate in parallel. The state switch may provide a signal to a GPIO (general purpose input-output) of the processing circuitry indicating that the battery has been disconnected. Immediately after the battery is disconnected, voltage is maintained for a brief period due to the capacitance of the circuitry, which enables the processing circuitry to take certain steps to avoid device misbehaviors.
