Abstract
The utility model discloses a test clamp of a low voltage electric appliance switch. The test clamp comprises a base plate. Two groups of wiring components arranged to be symmetrical are installed on the base plate. Each wiring component comprises a support frame, a transverse plate, a connection plate and a handle. The support frame is fixed on the base plate. One end of the transverse plate is hinged to the support frame. One end of the connection plate is hinged to the middle part of the transverse plate. The bottom of the handle is hinged to the lower part of the transverse plate on the support frame, and the middle part of the handle is hinged to the other end of the connection plate. An insulation block is fixed at the other end of the transverse plate. Three test needles connected with a test apparatus are arranged on the insulation block. When a low voltage electric appliance switch is placed on the base plate between the wiring components, the handle is pressed. Through linkage, the test needles can be connected with three electrode output terminals of the low voltage electric appliance switch. The test clamp has beneficial effects: the structure is simple, the cost is low, wiring work with a test device can be completed rapidly and the test clam is convenient for various function tests of a switch.
