Why is it dangerous to use a push-botton switch in the bathroom?

Using a push-button switch in the bathroom can be dangerous due to the presence of moisture, which increases the risk of electrical shock. Water and electricity do not mix, and if the switch is not properly insulated or rated for wet locations, it could lead to short circuits or electrocution. Additionally, wet hands can inadvertently create a conductive path, raising the likelihood of accidental activation or injury. It's crucial to use switches designed for bathroom environments, typically with appropriate waterproofing and safety features.
