Working principle:
By external mechanical force transmission elements (by pins, buttons, levers, rollers, etc.) will be used to force action on a reed, producing reed instantaneous action when action shifted to the critical point, so moving contact with the fixed contact spring at the end of the action point fast on or off.
When the force is removed on the drive components, action reed produce reverse action force transmission element reverse stroke when the action reaches a critical point reed, instantaneous reverse action.
Feature: contact spacing is small,short stroke action,according to the power of small,fast-break

MicroPython is a full implementation of the Python 3 programming language that runs directly on embedded hardware like Raspberry Pi Pico. You get an interactive prompt (the REPL) to execute commands immediately via USB Serial, and a built-in filesystem. The Pico port of MicroPython includes modules for accessing low-level chip-specific hardware.
What is Raspberry Pi Pico?
Raspberry Pi Pico, a microcontroller board built on silicon designed here at Raspberry Pi.
Your official guide
Microcontrollers, like RP2040 at the heart of Raspberry PiPico, are computers stripped back to their bare essentials. You don’t use monitors or keyboards, but program them to take their input from, and send their output to the input/output pins. Using these programmable connections, you can light lights, make noises, send text to screens, and much more. In Get Started with MicroPython on Raspberry Pi Pico, you will learn how to use the beginner-friendly language MicroPython to write programs and connect up hardware to make your Raspberry Pi Pico interact with the world around it. Using these skills, you can create your own electro‑mechanical projects, whether for fun or to make your life easier.
