A switch guard is a product that prevents incorrect operation of switches installed on machinery. This prevents a machine that operates near a worker from being turned on or off accidentally, and a rigid case also guards against damage to the switch's main bodies themselves. The lineup includes categories such as push-buttons, illuminated push-buttons and toggles. Products are installed using the supplied screws or magnets. For the emergency stop switches of machines such as semiconductor manufacturing installations, machine tools, food machinery or medical equipment, the guards also function to prevent time and production losses while maintaining safety. Materials include polycarbonate, polyamide resin and metal, while related products include drip-proof plates, and gas-proof and dust-proof covers.
