Abstract:
A low cost convoluted test strip for testing a battery powered device, the strip being positionable between terminals of a power supply circuit incorporating the battery, comprising:an elongated, flexible insulating layer defining upper and lower sides and first and second ends; an upper conductive layer on the upper side; a lower conductive layer on the lower side, the conductive layers being substantially electrically insulated from one another by the insulating layer; and, a convoluted portion adjacent to the first end of the strip, such that a portion of the lower conductive layer is cantilevered above and resiliently suspended with respect to an adjacent non-cantilevered portion of the upper conductive layer whereby the cantilevered portion of the strip can be depressed with respect to the non-cantilevered portion of the strip to establish electrical continuity between the conductive layers.
