摘要： PROBLEM TO BE SOLVED: To enhance the stability and reliability of control and achieve miniaturization. SOLUTION: This switch includes a control button biasing part 7 having a return spring 25 which biases a control button 3 in the clockwise direction and a resetting mechanism 8 which, when the control button is rotated counterclockwise, holds the return spring 25 of the part 7 compressed to lock the sliding element 16 of the part 7. The resetting mechanism 8 comprises a fitting element 17 which is fitted into the sliding element 16 of the part 7 when the return spring 25 of the part 7 is compressed, a spring 18 biasing the fitting element 17 toward the part 7, and a solenoid 19 secured to the fitting element 17 via the spring 18. The solenoid 19 has a movable core 20, a coil 21 wound on the movable core 20, and a fixed core 22 secured to one end of the coil 21, and releases the fitting element 17 from the state of being fitted in the sliding element 16 of the part 7 by moving the movable core 20 toward the fixed core against the biasing force of the spring 18, by means of a magnetic field produced by passing electricity to the coil 21. Thereby the control bottom 3 is reset.

摘要： PURPOSE:To provide a trigger switch of high operation stability and reliability, and achieve compactness of a power tool. CONSTITUTION:A pressure sensor 6 is fixed to a trigger operation member 32 of a trigger part 3 assembled in a switch case 2. Even when the number of usage times of a trigger button 31 becomes large, stable motor rotation speed can be maintained constantly. On/off switching of a power tool is performed not by switching action by contacts, but by press quantity applied on the pressure sensor 6, so operation stability and reliability become high, while achieving compactness of the power tool.

摘要： PROBLEM TO BE SOLVED: To provide an RF-MEMS switch with a simple structure, easy to manufacture, compactly constituted, and with its information signal and an on/off operation hardly affected by noise, and, therefore, capable of surely carrying out on/off changeover.
SOLUTION: The switch is made up by assembling a lower base plate 3 mounting a cantilever part 2, and an upper base plate at a cover side equipped with fixed-side RF input/output signal lines 4, 5. The cantilever part 2 provided at the lower base plate 3 constitutes a piezoelectric actuator, with its one end fixed to the lower base plate 3 and the other end having a contact part 6 on a top face in free up-and-down rocking movement. When the cantilever part 2 is bent upward, the contact part 6 also moves upward and comes in contact with both the RF input signal line 4 and the RF output signal line 5 on the upper base plate to electrically conduct the both lines 4, 5. Further, the lower base plate 3 does not exist under the rocking part of the cantilever part 2, with a space left there.
