Patent

CA 2636675

A polarity tester is engagable with an electronic communication port to test the polarity thereof. A connector is supported on a housing and features a plurality of electrical contacts for placement into electrical connection with a respective plurality of electrical contacts in the communication port when the connector is selectively engaged therewith. The plurality of electrical contacts include a power supply contact and a ground contact and a conductive path is defined within the housing to extend between the power supply and ground contacts. An indicator is connected within the conductive path to provide to a user of the polarity tester, when the connector is engaged with the communication port, an indication of whether electricity flows into the conductive path from the respective plurality of electrical contacts in the communication port through the power supply contact.
