Abstract
A trigger switch has a stationary contact and a moving contact provided inside a body and able to come close to and away from each other a contact drive member accommodated slidably inside the body to drive the moving contact, and an operating shaft having a first end engaging with the contact drive member and a second end which projects from the body, having a trigger configured to be operated by a user. Clearance is provided between the first end of the operating shaft and the contact drive member upon engagement, which enables inclination of the operating shaft relative to the contact drive member.
