A Switch Encoder is an electro-mechanical or solid-state component that translates the physical position or state of a rotary or linear switch into a digital signal. It is fundamental in devices requiring precise input control or menu navigation, such as industrial control panels, audio equipment, and robotics. By generating specific digital codes (e.g., binary or Gray code) for each position, it provides a reliable interface for a microcontroller to determine the switch's exact state, enabling accurate and responsive user input.
Switch Encoder is a frequency encoding device based on switch settings. It allows users to select between different voltage levels via a manual selector, forming a variety of encoding combinations. Each switch position is independently configured, enabling easy customization according to application requirements.
Switch Encoder combines precise mechanical design with reliable electrical performance, making it ideal for dual rotary encoder, dual rotary encoder with push button, rotary switch with push button, digital rotary switch, double rotary encoder, and dual axis rotary encoder applications. It provides accurate signal output and robust operation even in harsh industrial or commercial environments.
This device has become a critical component in automation, IoT systems, and other advanced control applications, including logistics tracking, medical instrumentation, and e-commerce inventory management.
