The SW-420 is a high-sensitivity, omnidirectional vibration sensor module, often used in security alarms, smart cars, and, with microcontrollers like Arduino, for detecting movement.

I'm in no way a CAD designer. With a caliper and Tinkercad I did the measurements to the best of my ability and produced the model with standard Tinkercad shapes. I needed this as a model for some of my sensors and I noticed that people only posted stl files related to the module and not the switch itself. Let me know your comments on this production. Thanks and enjoy.
