A vibratory compactor for compacting unhardened concrete, and the like, comprises an electrically operated vibration-generating unit having a first mount and a hand-grip unit having a second mount. A rod-shaped vibration-damping connector connects the units and has first and second end portions respectively joined with the first and second mounts. An electric cable supplies energy to the vibration-generating unit, and a switch arrangement selectively permits and interrupts the flow of energy through the cable. The switch arrangement comprises an actuator member mounted on the handgrip unit. The actuator member is movable to a first position permitting the flow of energy, and is permanently biased to a second position interrupting the flow of energy. The possibility of damage to the vibration-generating unit resulting from inadvertent extended operation of the same is prevented, and the compactor may be conveniently employed as a handtool.
