Abstract
A safety switch is a shell and has a base, a cover and two fasteners. The fasteners are detachably mounted on the base and the cover. The fasteners are made of resilient material more resilient than material for the base and the cover so the safety switch can keep the fastener from being broken. Furthermore, the fasteners can be arranged in different sizes to allow the safety switch to fit with different panels.
