A switch for e-textile projects that allows you to easily turn circuits on and off with a single click. Thanks to its latching mechanism, it works like a typical switch – one press turns on the power, and another cuts it off. Equipped with large "IN" and "OUT" contact pads, it allows for convenient sewing of conductive thread and quick connection of components such as LEDs or buzzers. Kitronik 2753
