When a person is having guests over, there may be some light switches that they may not want their guests to touch. The switch may turn on a light outdoors, or it may turn on another light that the host may not want turned on. If the guest forgets to turn off the light switch, the light that it turned on will be wasting electricity and it may even burn out the bulb. It is easily installed, and it sends the message that the light switch is not to be touched. The wall light switch cover can prevent a child from turning on a dangerous electrical appliance, or some other device hazardous to their well-being. The wall light switch cover is a useful invention that prevents light switches from being turned on and off. However, because one side is left open, the proper persons can turn on and off the light switch. The cover sends a blatant message to adults that the light switch should not be touched.
