  • Extended drive plate deliberate action rotary handle
    Patent number: 8115127
    Abstract: The present invention relates generally to a rotary handle. More particularly, the invention encompasses a deliberate action rotary handle. The invention further includes an extended drive-plate deliberate action rotary handle, such that to turn on a component, such as, a circuit breaker, requires a deliberate manual action by the user. If a deliberate action is not taken by a user but the handle is accidentally pushed then the handle does not engage with a drive shaft and the handle moves to an outer edge of a drive plate thus preventing the engagement of the handle with the other components to turn on the component.
    Type: Grant
