This testing machine is according to iec61058.1, iec60884 and iec60669.1 standards to design, it is suitable for household and similar fixed electrical installations switch capacity and normal operating life test. Its aim at checking the switch whether is able to withstand the mechanical damage and electrical fatigue damage in normal use, and if there are adhesion phenomena or prolonged closed or disconnected phenomena occur, inspect whether there are excessive wear and other harmful consequences with it. It is the special equipment for switch mechanical life machine and electrical life endurance tester.
