Abstract: A microphone switching apparatus for operating a recorder. The apparatus is incorporated into a hand microphone housing having a speaker, a microphone element, and an opening through which a control button for the apparatus extends. The apparatus is generally made up of a multi-region magnet movable along a path relative to a number of reed switches. Switching positions lie along the path which is defined by a slot in the apparatus frame corresponding to the opening in the housing. The control button is connected to a bolt which in turn is connected to the magnet. Movement of the button to the various switching positions will result in a combination of the reed switches being picked and dropped by the magnet. The picking and dropping of the reed switches will provide operating signals to the recorder. Also, maintaining the control button at two of the switching positions requires operator control in that if the operator releases the button, it will spring back to a previous position. Springs indirectly acting against the magnet cause the button to spring back to the previous position. As to the remaining positions, springs also indirectly act against the magnet, but latching means will maintain the button in place in the absence of operator control.
