Abstract
An electrically operated tool is disclosed for inserting one or more insulated electrical wires into a barrel shaped, slotted terminal. A modified solenoid provides a hammer action power stroke which is initiated by partially retracting the toolhead inwardly of the tool upon movement of the tool against the barrel terminal. A trigger circuit applies line voltage to the solenoid windings, saturating the core, to provide rapid power stroke, so that the solenoid armature hammers against a strike plate of the toolhead. The trigger circuit includes a high and low power adjustment.
