A waterproof switch functions just like an ordinary switch but keeps water out. These devices find use outdoors, or indoors in bathrooms, where the risk of electric shock is higher because of wet conditions. Furthermore, buyers can opt for standard, push-button, toggle, or rocker types.
Moreover, waterproof switches on boats are of the 12 V DC variety and function well despite splashes and the elements. Use waterproof switches in wet areas to promote safety and keep equipment functioning normally.
