  • Patent number: 5111009
    Abstract: A mechanism is provided for throwing several toggle switches together, especially toggle contact breakers, which are enclosed in an explosion proof container. A link between the toggles distributes manual toggling force over all of them from a single manual throw switch. The single manual throw switch may be located outside the explosion proof container and be connected to the link to the toggles through a wall, e.g., a moveable wall such as a door. In one practical embodiment, the link is an elongate tie bar for the toggles, and the manual throw switch is connected to the spaced apart forks which are geared together.
