Some devices require emergency switches. This product can quickly shut down the devices and reduce risks. Meanwhile, most electronic products are never truly turned off, which causes them to consume a small amount of current and poses safety risks. With our extended inline switch, you can easily turn your device on or off without unplugging it, which is more convenient. This emergency stop switch is made of high-quality plastic and metal, with a waterproof and flame-retardant casing and stable working performance.
