Abstract
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.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
84 words
A hand microphone multi-position switching apparatus operable with a single control button, said apparatus comprising: a. means having a generally arcuate shaped opening for defining a path along which said button is moveable and switch positions are located; b. a plurality of reed switches for defining said switch positions upon activation and deactivation; and c. a rotatably shiftable magnetic activating means movable by said button relative to said plurality of reed switches for activating and deactivating a combination of said plurality of reed switches.
Claim 2
Dependent Claim
84 words
A hand microphone multi-position switching apparatus operable with a single control button, said apparatus comprising: a. means having a generally arcuate shaped opening for defining a path along which said button is moveable and switch positions are located; b. a plurality of reed switches for defining said switch positions upon activation and deactivation; and c. a rotatably shiftable magnetic activating means movable by said button relative to said plurality of reed switches for activating and deactivating a combination of said plurality of reed switches.
Claim 3
Dependent Claim
20 words
An apparatus according to claim 1 comprising a number of spring means for biasing said activating means in first position.
Claim 4
Dependent Claim
15 words
maintaining said control button and said activating means in a second position along said path,
Claim 5
Dependent Claim
15 words
maintaining said control button and said activating means in a second position along said path,
Claim 6
Dependent Claim
33 words
An apparatus according to claim 1 wherein said arcuate shaped opening has oppositely and spaced radiating portions opening therein and extending along radii from a pivot about which said activating means is rotatable.
Claim 7
Dependent Claim
59 words
maintaining said control button and said activating means in a third position along said path, and d. a plurality of reed switches positioned relative to said path for applying signals to a recorder upon picking and dropping of said reed switches by said activating means when said activating means is moved relative thereto upon movement of said control button.
Claim 8
Dependent Claim
59 words
maintaining said control button and said activating means in a third position along said path, and d. a plurality of reed switches positioned relative to said path for applying signals to a recorder upon picking and dropping of said reed switches by said activating means when said activating means is moved relative thereto upon movement of said control button.
