摘要： An electric tool is provided. The electric tool has a more compact switching mechanism with durability increased by elimination of contacts. This electric tool includes a controller which controls power supply to the motor in response to operation of a switch lever which turns rotation of the motor ON and OFF. The electric tool includes a magnetic body (53) provided on a movable arm (52) which is moved by means of a switch lever (51), and a first and second magnetic detection units (Hall ICs (55, 56)) provided adjacent to the range of motion of the magnetic body. The first magnetic detection unit (55) detects the approach of the magnetic body when the switch lever is in the motor OFF position, and the second magnetic detection unit (56) detects approaching of the magnetic body when the switch lever is in the ON position. The controller uses the two detection results to determine the switch lever position. The magnetic detection units (55, 56) are accommodated in a casing (61) which is isolated from a cooling wind path.

摘要： A fastener driving tool is provided which performs driving only when a trigger lever is turned ON following a push lever. The fastener driving tool includes a sleeve valve driving a driver blade, and in the sleeve valve, supply and exhaust of compressed air are controlled by a trigger valve 51. The trigger valve 51 includes a valve piston 61 movable between an air-supply position where the valve piston 61 causes an opening part 54 and a communication port 56 to communicate with each other and blocks an exhaust port 55, and an exhaust position where the valve piston 61 blocks the opening part 54 and causes the exhaust port 55 and the communication port 56 to communicate with each other, and a plunger 67 movable between a communication position where the plunger 67 causes compressed air in a pressure accumulation chamber to be supplied to a pressure chamber 66 and a shutoff position where the plunger 67 shuts off communication between the pressure accumulation chamber and the pressure chamber 66 and causes air in the pressure chamber 66 to be exhausted. When a trigger 41 and a push lever 44 are in striking stop positions, the plunger 67 is driven to a communication position by a trigger arm 76.
