Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
158 words
A handle for an electrically operated apparatus comprising a body portion for gripping said handle, said body having an elongated portion and a shorter portion extending at an angle from said elongated portion, connector means at each end of said body for connecting an electrical cord and an electrical device through said handle, said connector means allowing said cord and device to be insertable in either end of said handle interchangeably, means within said handle for electrically coupling said connector means at each end of said handle, a switch actuator extending from said body and a switch mounted within said body in a manner so as to be activated by said switch actuator, said switch being electrically coupled to said connector means so as to make and break the circuit between said connector means, and wherein said switch actuator extends along the top of said body in the region bridging where said elongated portion meets said shorter portion.
