A LED cartridge assembly for use in a polarity testing probe fits into a cavity in the handle of the probe with first and second assembly contacts to contact the first and second testing probe contacts, respectively. The handle is transparent through to the cavity. The assembly has two LEDs, the first LED conducting when current flows in one direction, the second LED conducting when current flows in the opposite direction. The assembly has a transparent holder with wells to receive the LEDs. The assembly has a spring contact at one end and a button contact at the other. The assembly can be used to easily convert existing non-polarity testing probes to polarity testing probes. The assembly can be used with packages that contain two LEDs as an integrated unit for placement in a single well of the holder.

L'invention porte sur un ensemble cartouche à diodes électroluminescentes à utiliser dans une sonde de vérification de la polarité. La cartouche s'insère dans une cavité du manche de la sonde, et ses premier et second contacts touchent respectivement les premier et second contacts de la sonde de vérification. Le manche est transparent jusqu'à la cavité. L'ensemble cartouche comprend deux diodes électroluminescentes, la première étant conductrice lorsque le courant passe dans un sens et la seconde, lorsque le courant passe dans le sens opposé. L'ensemble comporte un manche transparent avec des logements pour recevoir les diodes électroluminescentes, un contact à ressort à une extrémité et un contact à bouton à l'autre. Il peut servir à convertir facilement des sondes de vérification de non-polarité en sondes de vérification de la polarité. Il peut également être utilisé avec des appareils qui comprennent comme unité intégrée deux diodes électroluminescentes à insérer dans un seul logement du manche.
