AI Technical Summary

Technical Problem

Existing self-resetting sealed toggle switches have poor synchronicity when the number of poles is large, which can easily cause flight control systems to delay connection and misjudge the connection. In addition, their sealing performance is generally poor.

Method used

The combination structure of spherical pivot, cover, sealing gasket, sealing hopper and sealing ring, combined with brass and polytetrafluoroethylene, is designed as an L-shaped cross-section sealing component to ensure waterproof, dustproof and gas-proof between the switch handle and the housing, and improves synchronization through elastic energy storage components.

Benefits of technology

It improves the sealing and synchronization of the switch, ensures good sealing performance under different ambient temperatures, reduces the resistance of the handle rotation, and enhances the reliability and service life of the switch.

Abstract

The application discloses a self-resetting sealed toggle switch structure, which comprises a switch handle, a switch shell and a sealing component. The switch handle has a spherical fulcrum part. The switch shell has a shell top wall, and a top wall notch is formed on the top surface of the shell top wall and surrounds the periphery of the spherical fulcrum part. The top wall notch and the spherical fulcrum part jointly define a top wall groove with an upward opening. The sealing component is composed of a cover, a sealing gasket, a sealing bucket and a sealing ring. The application has the beneficial effects of providing excellent sealing for the toggle switch and ensuring the waterproofness, dustproofness and gasproofness between the switch handle and the switch shell.
