Document Type and Number:
Japanese Patent JP6675296
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power tool capable of detecting operation states in three or more stages in an operation moving member with a relatively simple configuration.SOLUTION: A power tool includes: a working tool rotated by an electric motor incorporated into a power tool body; trigger switch means 20 for changing a rotational speed of the electric motor; and rotational speed setting means (controller) for setting the rotational speed of the electric motor on the basis of a detection signal from the trigger switch means 20. The trigger switch means 20 includes: an operation moving member which is slidably mounted in the power tool body 2; first and second magnets 52 and 54 disposed so as to mutually face; and magnetic flux detection means 56 arranged between the first and second magnets 52 and 54. The rotational speed setting means sets the rotational speed of the electric motor 10 on the basis of a detection signal from the magnetic flux detection means 56.SELECTED DRAWING: Figure 2
