Testing device for electronic circuits and especially for portable radios

A portable communication device comprising a housing, a printed wiring board mounted in said housing, an electronic circuit mounted on said printed wiring board and a battery compartment on a portion of said printed wiring board to receive a battery, an auxiliary connector for test use, said auxiliary connector including a magnet and a connecting terminal, said battery compartment including a contact for making a connection to one electrode of said battery in said compartment and a test terminal adjacent said contact and connected to said electronic circuit, said contact and said test terminal being interconnected through said connecting terminal of said auxiliary connector to place said electronic circuit in condition for conducting a test operation when said auxiliary connector is removably mounted over said battery compartment under an attraction of said magnet.

A device for testing electronic equipment comprising a battery compartment having a plurality of terminal contacts associated therewith, means for connecting at least one of said terminal contacts to a circuit test point in said electronic equipment, audible signal means, means for connecting at least another one of said terminal contacts to said audible signal means, means for applying battery power to still another of said terminal contacts, separate means which is positionable for selectively bridging predetermined ones of said terminal contacts in order to by-pass at least some of said electronic equipment and to enable a sounding of said audible signal means for test purposes, said separate means comprising a plate-like conductive member with projecting extensions configured to engage selected ones of said terminal contacts, and magnetic means attached to said plate-like conductive member for securely holding said plate in association with said battery compartment, in said bridging position.
