ABSTRACT:
An electromagnetic stapler having a staple driving circuit with an actuating switch, and having a levered trigger which is depressed by the user so that the lever actuates the switch, whereinafter actuation, a moving element of staple driving mechanism strikes the lever causing disengagement of the lever from the switch so that only one shot is permissible unless and until the trigger is again depressed. The trigger is useful in mechanically providing a safety one shot control for a conventional stapler having a continuous repetitive electrical driving circuit, and the trigger is readily mounted with a conventional stapler. A stapler may alternatively house a trigger permitting a continuous repetitive staple drive, or the trigger of the present invention which provides a one shot staple drive.
