Publication number: 20250014846Abstract: A trigger switch capable of suppressing wear of a sliding electrode part and a device including the trigger switch are provided. A trigger switch includes a front sub-brush and a rear sub-brush that, when a drive part is driven by a movement of a trigger caused by a push-in operation to the trigger, move from an on-position where they contact a front sub-electrode and a rear sub-electrode on a substrate to an off-position where they do not contact the front sub-electrode and the rear sub-electrode. As the front sub-brush and the rear sub-brush move from the on-position to the off-position, a contact between the front sub-brush and the rear sub-brush and the substrate are released.Type: ApplicationFiled: June 6, 2024Publication date: January 9, 2025Applicant: OMRON CorporationInventors: Kohei SUGIYAMA, Kazushi MAETA, Yohei TSUKANAKA, Akihiro ISHII, Daiki ANDO, Takumi FUJIHARA
