In one embodiment, there is a fault interrupter device comprising at least one sensor comprising at least one first transformer having at least one outer region forming an outer periphery and at least one inner hollow region. There is also at least one second transformer that is disposed in the inner hollow region of the at least one first transformer. The transformers can be substantially circular in configuration, and more particularly, ring shaped. In another embodiment there is a rotatable latch which is used to selectively connect and disconnect a set of separable contacts to selectively disconnect power from the line side to the load side. The rotatable latch is in one embodiment coupled to a reset button. In at least one embodiment there is a slider which is configured to selectively prevent the manual tripping of the device.

A power tool includes a housing, an electric motor, a switch, an operating element, a contact rod, a pressing block, and a reset element. The electric motor is disposed in the housing. The switch includes a trigger point for controlling the electric motor to be turned on. The operating element is operated so that the switch is triggered. The contact rod is supported by the housing, where the operating element is capable of pushing the contact rod to move. The pressing block is elastically connected to the contact rod and capable of being driven by the contact rod to push the trigger point. The reset element is connected to the contact rod.
