What is Sealed Subminiature Micro Switch?

Sealed Subminiature Micro Switches combine ultra-small size, sealed protection, and highly reliable snap action performance, designed for applications requiring high integration and operating in challenging environments. Sealing is its most prominent feature, meaning the housing is encapsulated in epoxy resin, and the pins are also sealed. Utilizing alloy contacts, it maintains stable conduction even at low currents, making it widely used in automotive micro switches, home appliances micro switches, and industrial equipment micro switches.

Features of the Sealed Subminiature Micro Switch

I. Ultra-Compact Subminiature Design: These microswitches feature an ultra-compact form factor, integrating a complete snap-action contact mechanism within a tiny volume (detailed dimensions can be found in the technical documentation). This meets the requirements of high integration and lightweight design, making them suitable for compact electronic modules.

II. Sealed Construction with High Protection: As a waterproof micro switch, it effectively prevents the intrusion of moisture, dust, and contaminants through processes such as rubber sealing rings, thin-film sealing, or overall potting. The protection level typically reaches IP67.

III. Long Mechanical & Electrical Life: High-quality contact materials, spring structure, and sealing design ensure stable mechanical and electrical performance even under high-frequency operation and complex environments.

IV. Customization Available: The products are equipped with various types of operating handles and a full range of terminal blocks, with different contact types available (SPDT, SPST-NC, and SPST-NO) to meet the diverse application needs of different customers.
