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.

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.

A trigger switch performs speed control of a motor according to a pull-in amount of a trigger. A wiring path for lead wires connects the trigger switch and an auxiliary device. The wiring path is formed in an insulating wall. The insulating wall isolates a pair of power supply terminals, each connected to a power supply, from each other.

In an electromagnetic coil drive device an operation coil excites an electromagnet. A switching element is turned on and off by application of a pulse signal thereto and supplies the operation coil with a power supply voltage. A voltage detecting circuit detects the power supply voltage and a gain circuit delivers a closing level signal in accordance with the voltage detected by the voltage detecting circuit. The gain circuit also delivers a holding level signal based on the detected voltage after a predetermined period of time. The level of the holding level signal is higher than that of the closing level signal. A reference wave generating circuit generates a triangular wave. A comparing circuit compares the triangular wave with the closing level signal to thereby generate a closing pulse signal having a predetermined cycle. The comparing circuit also compares the triangular wave with the holding level signal after the predetermined period of time to thereby generate a holding pulse signal having a duty ratio smaller than that of the closing pulse signal. An on-off drive circuit supplies the switching element with the closing and holding pulse signals.
