What is the waterproof push button switch?

Waterproof push button switch is used in places with water or outdoors(make sure there will be no rain into the switch to cause the switch to burn), normally, the waterproof rating of the push button is IP65, IP67, IP68.

The main difference between IP67 and IP65 is that the waterproof rating is different. According to IEC 60529, 5 stands for protection against spray water immersion(protection against low-pressure spray lasting at least 3 minutes).

The 7 stands for protection against immersion(30 minutes of immersion in water up tp 1 meter deep). Therefore, IP67 waterproof grade is higher than IP65.

IP68, the test time is at least 1 hour of continuous immersion in water. The depth is usually 2m specified by the manufacturer.
