Title: CONTACT STRUCTURE FOR SWITCH, TRIGGER SWITCH AND ELECTRIC POWER TOOL
Abstract:
The purpose of the present invention is to increase contact contact-force and improve vibration resistance. In the present invention, a switch opening/closing mechanism (7) is provided with a sliding part (6d), a second movable piece (31), and a second fixed contact (31b). When the movement amount of the sliding part reaches a second retraction amount, the second movable piece (31) comes into contact with the second fixed contact (31b) due to a spring force that acts on the second movable piece (31), and when the movement amount of the sliding part reaches a third retraction amount which is greater than the second retraction amount, the sliding part presses the second movable piece against the second fixed contact.
