You don't need a switch to make a leaf pendant. Adding a switch to the leaf-making pendant will make it inconvenient to carry and increase the weight. Pendants can't be made into a single piece, and they are mainly used with rope chains. For example, although the materials are varied, mainly jade, dewaxed glass pendants and so on. Generally used to hang on mobile phones, MP4s, etc. For decoration. Or around your neck or wrist.
