Switch must be cycled through each function and position as described in service life test cycle table to complete one cycle of test for durability. Temperature could vary from -40 degrees Celsius to 85 degrees Celsius depending on the vehicle position. Humidity at ambient shall be 85%. Number of cycles to be met for the different switches is shown in the durability test table.All DUT functions shall remain FSC A when tested in the supply voltage ranges given above. Activation forces shall be within specification and open circuit resistance, voltage drop/contact resistance and contact bounce requirements.
