Abstract:
A push switch capable of indicating a push state comprises a cap, movable stand, base, connecting member, light-emitting module, resilient component, circuit unit, and casing. The cap comprises a surface layer onto which a first UV ink layer, translucent chromium-plated layer, and second UV ink layer are sprayed sequentially. The connecting member is light-penetrable and fitted to the bottom of the cap. The movable stand comprises a body, connecting end portion connected to the connecting member, and limiting portion extending laterally from the body. The movable stand moves whenever the cap is pushed. The base has therein a receiving space. The light-emitting module, resilient component, and circuit unit are disposed in the receiving space. After at least one light-emitting component of the light-emitting module has emitted light, brightness and color of the light emitted is visible through the cap to indicate the push state of the push switch.
