Question 190Electricity & Electronics - 1st Asst/Chief

You are correct, the answer A) Rapid corrosion of switch components is the right answer. If the cover gasket on the winch master control switch becomes deteriorated, it can allow moisture and contaminants to enter the switch enclosure. This can lead to rapid corrosion of the electrical contacts and other metallic components inside the switch. The corrosion can disrupt the proper functioning of the switch, potentially causing issues with the operation of the winch. The other answer choices are incorrect because: B) Contamination of lube oil is not a direct consequence of a deteriorated cover gasket on the control switch. C) Sparking at the winch motor brushes is not a likely outcome of a deteriorated control switch gasket. D) Overheating of the winch motor is also not a direct result of the control switch gasket issue.
