In view of the above problem, the present invention is to provide an electrical power tool which enables a user to intuitively grasp a rotation direction and a rotation speed of a tip tool. The electrical power tool 1 comprises a chuck 2 provided at a tip of a tool body 3, and rotatable with a tip tool held, and an operation switch 7 having operation protrusions 6 exposed to both side surfaces of a tool body 3 so as to be able to operate, respectively bilaterally symmetrically protruded with a rotation axis of the chuck 2 therebetween, coaxially rotatable with the chuck 2, and urged so as to be self-restored to a neutral position. The chuck 2 is rotated in a direction according to a rotation direction of the switch 7 at a speed according to a rotation angle from the neutral position of the operation switch 7.

An electric tool switch has an operation member turnable in both directions and biased to self-return to a neutral position, a circuit substrate arranged to be orthogonal to a turning shaft of the operation member, a slidably moving element which is pressed against the circuit substrate and which is turned with the operation member to slidably contact the circuit substrate, and an inversion mechanism for switching a polarity between output terminals according to the turning direction of the operation member from the neutral position. The circuit substrate is formed with two sets of variable resistor circuits, which close a circuit when the slidably moving element slidably contacts and which resistance value changes according to a contacting position of the slidably moving element, electrically connected in parallel on both sides in the turning direction from a position corresponding to the neutral position of the operation member.

An electrical connector has a plurality of terminals arranged side-by-side in a horizontal direction. Each of the terminals has a first connection portion adapted to be connected with one of two members electrically connectable to each other via the electrical connector, and a second connection portion adapted to be connected with the other member. In the electrical connector, two or more first terminals consisting of a part of the terminals are arranged such that an inter-terminal pitch in the first connection portions thereof is equal to that in the second connection portions thereof, and two or more second terminals consisting of the remaining terminals other than the first terminals are arranged such that an inter-terminal pitch in the first connection portions thereof is less than that in the second connection portions thereof.
