Publication number: 20230045987Abstract: A trigger switch includes a trigger, a casing, a compression spring, and a sealing member. The trigger includes a trigger body to which a force is applied when an operator performs a pushing operation, and a trigger shaft extending from the trigger body toward a pushing direction. The casing holds the trigger so as to guide the trigger shaft along the pushing direction when the pushing operation of the trigger is performed. The compression spring is fitted to the outside of the trigger shaft between the trigger and the casing. The sealing member is disposed between the trigger and the casing so as to be fitted to a further outside of the compression spring and cover the trigger shaft and the compression spring.Type: ApplicationFiled: January 28, 2021Publication date: February 16, 2023Applicant: OMRON CorporationInventors: Takumi FUJIHARA, Taiki KOYAMA, Kazushi MAETA
