Title:
スイッチの接点構造、トリガースイッチ及び電動工具
Document Type and Number:
Japanese Patent JP6690525
Kind Code:
B2
Abstract:
The switch opening-closing mechanism, which makes it possible to increase a contact force so as to improve a vibration resistance, includes a sliding part, a second movable piece, and a second fixed contact. In a case where an amount of movement of a sliding part reaches a second retraction amount, the second movable piece comes into contact with the second fixed contact due to a spring force applied to the second movable piece. In a case where the amount of movement of the sliding part reaches a third retraction amount which is larger than a second retraction amount, the sliding part presses the second movable piece against the second fixed contact.
