BRIEF DESCRIPTION OF LUMINOUS SWITCH

Some switches are equipped with luminous function, so that you can easily find the position of the switch when the light is dark at night, but you must distinguish between the paint (phosphor) type and the power-emitting type when buying. The price of the former is lower, but because the phosphor disappears after the external light source , The energy is quickly exhausted, and it can't play the role of fluorescence for a long time, while the power-emitting type can emit light for a long time.
