Crash sensor, also known as snap-action switch, is an electric switch that is actuated by very little physical force.
It is a digital on-off input module necessary for elementary electronic.
By programming, it can be used for the light, sound device, key function of LCD display, 3D Printer position feedback, or other devices.
This sensor needs to be used together with EASY plug control board.

Special Note:
The sensor/module is equipped with the RJ11 6P6C interface, compatible with our keyestudio EASY plug Control Board with RJ11 6P6C interface.
If you have the control board of other brands, it is also equipped with the RJ11 6P6C interface but has different internal line sequence, can’t be used compatibly with our sensor/module.
