I. Introduction

– Explanation of IP67 waterproof micro switch

An IP67 waterproof micro switch possesses specialized features that enable it to withstand harsh environmental conditions. This makes it suitable for applications where exposure to moisture, dust, and other contaminants is prevalent.

II. Features of IP67 waterproof micro switch

– Definition of IP67 waterproof rating

The term “IP67” stands for “Ingress Protection” followed by two digits. The first digit (6 in this case) refers to the level of protection against solid objects, while the second digit (7) denotes protection against liquids. Here’s what each digit signifies:

6 (Protection against Solids): The digit 6 indicates that the micro switch is dust-tight, meaning it prevents the ingress of dust and other solid particles that could potentially interfere with its operation.

7 (Protection against Liquids): The digit 7 signifies that the micro switch is capable of withstanding immersion in water up to a depth of 1 meter for 30 minutes without allowing water ingress. This level of protection ensures the switch remains operational even when exposed to rain, splashes, or temporary submersion.
