Testing of an electric starter switch was accelerated from a normal rate of 5 cycles per hour to an accelerated rate of 1 cycle every 20 seconds. At the accelerated rate, failure times were Weibull with an estimated shape parameter of 1.8 and an estimated characteristic life of 5000 hours. What is the reliability of the switch under normal use over a I-year period (24 hours a day)?
