PROTECTIVE CONSTRUCTION
Expresses the degree of protective construction that guards the level of functionability of the switch against ingress of solid
objects, water, and oil. The standards are IEC529 (IEC: International Electrotechnical Commission) standards. IEC standards
determine the level of protection against both water and solid objects, but not against oil.

Note: 1. All of the tests cited above were conducted with the cord vent (conduit vent) tightly shut.

2. The above protective constructions are based on IEC standard but major differences may arise due to length of use and operating environment.
3. When the corrosion-proof model is immersed in water for 30 minutes or more, verify that no water has penetrated the inside before use.
This should be thoroughly discussed and verified.
