The field of industrial automation usually involves wet, humid environments, metal push button switches should have a certain waterproof level (such as IP67 or higher).
Waterproof design considerations: The use of seals, coatings, waterproof gland and other measures to ensure that the switch can still work normally in the case of water activation or water splashing.
Example: In wet environment of the food processing industry, use our PS series piezo switch which is IP69K grade with special seal design and stainless steel material(SS316L) to resist high pressure water flow and liquid splash.
