The self-locking switch is a commonly-used button switch that outputs digital signal. When pressed down once, its circuit is connected, keeping in self-locking mode; when pressed again, the button switch is disconnected and ejected. It works well with maincontrollers such as micro:bit and Arduino, and can be used for not only Mind+ and makecode graphical programming but also non-programming projects. Connect this module to other output ones in parallel to realize all kinds of functions now!
