The device was returned to the manufacturer for repair and evaluation.The service record indicates that the device was manufactured on 04/05/2011 and was last repaired on 06/05/2013 for a non-related issue.Evaluation of the device observed that the power switch was recessed into the electric dermatome and the device did not operate.The power switch was observed to be separated in half at the upper and lower casings.Prior to repair, the electric dermatome was within calibration specifications at all tested thickness settings.In post-repair, the motor operated within motor voltage specifications.Customer returned a power supply.There was no visible issues with the device and met all functional specifications prior to repair.While the switch casing was observed to be nicked and bent, the timing of the event is unk as the switch could have been damaged by the customer or from disassembly during the repair process.It is known, however, that the switch was separated at the upper and lower casing prior to repair, since it is physically impossible for the switch to be recessed otherwise.Known information and investigation findings support the cause of the customer's reported event to be improper handling, as excessive downward force upon the switch button likely caused the switch casings to separate.Improper handling was most likely the cause for the damaged switch, which most likely caused the customer's reported event.The device was serviced and returned to the customer.
