A brief introduction to waterproof tactile switches

　　Introduction to waterproof tactile switches

　　Low-voltage rectification and filtering circuit of waterproof tactile switches: The pulsating voltage after being stepped down by a high-frequency transformer also needs to be rectified and filtered using diodes and capacitors. The capacitors used in the rectification part must not have too high an AC impedance; otherwise, the high-frequency AC components cannot be filtered out. Therefore, the selected capacitors must not only have a large capacitance but also a low AC resistance. Additionally, one or two large inductors with magnetic cores can be seen, which, together with the filtering capacitors, filter out high-frequency AC components to ensure a pure DC output. Pressing the spring contact connects the printed circuit.

　　Nowadays, manufacturers of waterproof tactile switches are mainly concentrated in the Yangtze River Delta and Pearl River Delta regions. Most products are produced in these areas. With the development of electronic information products towards digitization, networking, integration, and portability, composite components and integrated passive components have become the main direction of electronic component development. Multilayer ceramic technology and low-temperature co-fired technology have become mainstream technologies to achieve "multilayer passive components, multilayer chip components, chip component integration, and functional component composite and modularization."

　　Composite and integrated solutions are the best ways to reduce the installation costs of passive components. At the same time, due to the reduction of solder joints and wiring, product reliability can be improved, and the operating speed of digital circuits can be increased. With the high-frequency development of wireless communication and the high-speed processing of data, microwave component technology has become a major hotspot.
