A switch for operating an electric device, the switch having a released position in which the device can be switched on or off, and a locked position in which switching on of the device is prevented, in combination with a removable key element including a key insertable into the switch and displaceable for placing the switch in a selected one of the released and locked positions. The switch includes a function element fixedly disposed within the electric device, and an actuating element for switching the electric device on and off, seated on the outside of the device and in operative connection with the function element. The key element is composed of a cap-like slip-on element to which the key is permanently fastened and which is configured to be securely and removably mounted on the actuating element.
