  • Patent number: 5738206
    Abstract: A child resistant switch lock having a body and a slide which can be installed over an existing mounted toggle-type or rocker-type switch. The slide is arranged to operate the toggle handle or rocker between an on and off positions. Stopping tabs on the body prevent movement of the slide from the off to the on positions unless the stopping tabs are first depressed. The required two handed operation, one to depress the stopping tabs and one to advance the slide, make operation by a child very difficult. The slide can operate the toggle handle of a toggle-type switch directly or the rocker of the rocker-type switch through intermediate cams contained in the body.
