I. Introduction: to complete the switch to the generic (including electric window switches, rocker switches, push button switches and rotary switches and shaped switches, etc.) of the durability test, enabling mechanical performance parameters and electrical performance parameters of the rocker switch durability testing, can be the same or different types of three endurance test switch simultaneously. Technical features and indicators: 1, the set and the move: software settings toggle, velocity and displacement screwing such action; (2) contacts through various stalls, and drop-off detection; set to fail contact drop by pressure drop value or number of failures is set to determine the results of product testing; 3, automatically determine the contact failure conditions, and can show which switch and contact problems; 4, divided into high and low temperature test bed type (-40 ~ 120 ℃, 10 ~ 95% RH), servo motor driven, stepper motor-driven variety of series 5, programmable DC electronic load power boxes, lighting load box, resistive load box load in the form of a variety of options. Second, to meet the standards: 1, QC / T 413-2002 "basic technical requirements of automotive electrical equipment." 2, QC / T 632-2000 "automotive rocker switch technical conditions." 3, QC / T 198-1995 "auto switch General technical conditions." Third, the test parameters: a DC power supply: 0 ~ 30V adjustable, 0 ~ 50A adjustable. 2, screwing angle: 0 to 360 degrees, accuracy: ± 0.5 degrees Toggle 0 ~ 100mm, can be set arbitrarily, press 0 ~ 50mm, adjustable. Fourth, the test subjects: automotive air conditioning panel switches, window lifter switch, car audio switch, eight seat switch, mirror switch, etc.
