Proximity switch surge test device and method

The invention provides a proximity switch surge test device and method.The device comprises an interface module, a test load and a detection indication module, the first input end of the interface module is used for being connected with a to-be-tested proximity switch, and the interface module is used for providing test voltage for the to-be-tested proximity switch; under the action of the test voltage, the proximity switch to be tested outputs an induction signal at the output end of the interface module; the input end of the test load is connected with the output end of the interface module, the output end of the test load is connected with one end of the detection indication module, and the test load is used for outputting test current according to the magnitude of the induction signal; and the detection indication module is used for controlling a display state according to the magnitude of the test current so as to judge whether the proximity switch to be tested is damaged or not in the test according to
