A probe extends from a two-part plastic housing. The first part has an externally threaded cylindrical section, which is adapted to mate in screw fashion with an internally threaded cylindrical section of the second part. A member is inserted between the parts and includes a cylindrical portion, receivable within the threaded section of the first part for structural reinforcement of the housing, and a flange, positioned adjacent the rim of the first part, to properly locate the member. In one embodiment, the first part and the member are provided with oppositely directed slots which align to form a radially extending channel through which a lead extends. The sides of the channel engage the lead to provide strain protection. A spare bulb mount is provided on the member and extends into a cavity formed in the second part. In a second, self-powered, embodiment, the structure of the member is modified to eliminate the bulb mount to permit a battery to be received within the cavity of the second part.
A circuit test device comprising a housing, a probe mounted to and extending from said housing, and a lead extending through said housing, said housing comprising:
A circuit test device comprising a housing, a bulb, means for mounting said bulb within said housing, a probe mounted to and extending from said housing and a lead extending through said housing, said probe and said load being operably electrically connected to said bulb, said housing comprising a first part, a second part, means for removably connecting said parts and a member adapted to be received within said housing, said member comprising means for mounting a spare bulb thereon.
A circuit test device comprising a housing, a bulb, means for mounting said bulb within said housing, a probe mounted to and extending from said housing, said probe being operably electrically connected to said bulb, means for mounting a battery within said housing, and a lead extending through said housing, said lead being operably electrically connected to said battery mounting means, said housing comprising a first part, a second part, means for removably connecting said parts, and a member adapted to be received within said housing between said bulb mounting means and said battery mounting means, said member comprising a passageway and means for operably electrically connecting said battery mounting means and said bulb, said electrical connecting means extending through said passageway in said member.
