The flex circuit provides solder less electrical connections among the electrical components of the hearing aid. The hearing aid also includes an actuator switch that allows the user to engage the hearing aid in an ON or an OFF mode of operation. Preferably, the actuator is electrically connected to the hearing aid without the use of solder. Connection between the first and second sections includes a mechanical securing mechanism, such as an interlocking joint.
