ABSTRACT:
A battery cable assembly having an in-line captive switch device, in which the battery cable conductor is divided into two parts, with a conductive contact pad electrically attached to the end of each part, the pads being axially aligned within the bore of a housing having a threaded sleeve member formed, at least partially, of insulating material. The first pad is secured within the sleeve in fixed non-rotating relation thereto, and in fixed position relative to the first cable portion. The second cable portion is provided with a threaded ferrule which is rotatable relative to the second cable portion for providing relative axial displacement between the pads. The rotatable ferrule is captively rotatable to preclude separation of the two cable portions. A blinking light-emitting device is electrically coupled to the two cable portions for energization via the storage battery and electrical circuit through the light-emitting device to provide visual indication when the pads separate.
