A sheet type membrane switch

Abstract

This utility model discloses a spring-loaded membrane switch, relating to the field of membrane switches. It includes a main body, with an integrator mounted on one end of its upper surface. Multiple circuits are embedded on the upper surface of the main body. An annular baffle is positioned above the end of the circuit furthest from the integrator. The bottom end of the annular baffle is fixedly connected to the upper surface of the main body. An internal thread is provided on the inner wall of the top of the annular baffle, and a threaded sleeve is provided inside the annular baffle. This utility model, by providing an annular baffle on the main body and threadedly connecting it to the threaded sleeve, fixes the conductive block at the bottom of the spring-loaded contact above the circuit. This facilitates replacement or maintenance of the spring-loaded contact when damaged or malfunctioning, improving the practicality of the device. The sealing ring ensures a tight seal between the annular baffle and the threaded sleeve, preventing corrosion at the contact point between the solder block and the contact head, thus extending the service life of the device.
