Power tool

A power tool comprising:

• an electric motor as a drive source,
• a start switch configured to start the electric motor, the start switch being movable between an OFF position and an ON position and being engageable or latchable in a lock-ON state, and
• an electromagnetic actuator configured to retract an actuation pin into a body of the electromagnetic actuator in response to an interruption of a supply of electric current to the power tool, and
• an intermediate lever operably interposed between the start switch and the electromagnetic actuator,
• wherein:
• the intermediate lever is configured to be tilted or pivoted by the retracting movement of the actuation pin of the electromagnetic actuator to disengage or unlatch the start switch from the lock-ON state and/or to block the start switch from engaging or latching in the lock-ON state.

A power tool comprising:

• an electromagnetic actuator configured to shift from a first configuration when the power tool and the electromagnetic actuator are connected to a source of electric current to a second configuration in response to the power tool and the electromagnetic actuator being disconnected from the source of electric current;
• an electric motor selectively connectable to the source of electric current by a start switch, the start switch being movable between an OFF position and an ON position and being latchable in a lock-ON state, and
• a lever having a first end at the actuation pin and a second end at the start switch,
• wherein shifting the electromagnetic actuator from the first configuration to the second configuration pivots the lever, and
• the start switch is configured to move from the lock ON state to the OFF position in response to the electromagnetic actuator shifting from the first configuration to the second configuration.

A power tool comprising:

• an electromagnetic actuator comprising an actuation pin, the electromagnetic actuator being configured to shift from a first configuration when the power tool and the electromagnetic actuator are connected to a source of electric current to a second configuration in response to the power tool and the electromagnetic actuator being disconnected from the source of electric current and
• an electric motor selectively connectable to the source of electric current by a start switch, the start switch being movable between an OFF position and an ON position and being latchable in a lock-ON state,
• wherein:
• the start switch is configured to move from the lock ON state to the OFF position in response to the electromagnetic actuator shifting from the first configuration to the second configuration, and
• the start switch is configured such that:
• the start switch has an end,
• moving the start switch from the OFF position to the ON position shifts the end in a longitudinal direction of the power tool, and
• moving the start switch from the ON position to the lock-ON state shifts the end of the start switch in a radial direction of a substantially cylindrical housing of the power tool.

A power tool comprising:

• an electromagnetic actuator configured to shift from a first configuration when the power tool and the electromagnetic actuator are connected to a source of electric current to a second configuration in response to the power tool and the electromagnetic actuator being disconnected from the source of electric current;
• and
• an electric motor selectively connectable to the source of electric current by a start switch, the start switch being movable between an OFF position and an ON position and being latchable in a lock-ON state,
• wherein:
• the start switch is configured to move from the lock ON state to the OFF position in response to the electromagnetic actuator shifting from the first configuration to the second configuration,
• the start switch is supported by a main-body housing such that it pivotable between the ON position and the OFF position,
• when the start switch is pivoted to the ON position, it is holdable in the lock-ON state by a tip part of a pivotable lock-ON lever abutting on a longitudinal end portion of the start switch,
• the lock-ON lever is pivotably supported by a rear-part case of the power tool that is connected to the main-body housing,
• the electromagnetic actuator is disposed and held on the lock-ON lever so as to move integrally therewith, and
• the lock-ON lever is spring-biased towards a lock-OFF position.
