Claims

[Scope of Claim for Utility Model Registration] (1) Consisting of a charging stand equipped with a charging terminal, a built-in fan motor and a storage battery, and a main body that forms electrical contacts and is provided with a connecting terminal and a movable terminal made of an elastic metal plate. , the connection terminal is provided with a flat part that comes into contact with the charging terminal and the movable terminal, and a rotation support surface bent approximately perpendicularly to the flat part, and has a generally semicircular shape that includes the bent corner and extends in the longitudinal direction to the flat part. A switch device for a battery-powered vacuum cleaner, which has a reinforcing bead formed therein and a contact point formed by the reinforcing bead. (2) The reinforcing bead has a substantially semicircular cross section that is convex toward the side that comes into contact with the movable terminal, and the contact is formed by a bead with a substantially semicircular cross section that is formed perpendicular to the reinforcing bead on the movable terminal. A switch device for a battery-powered vacuum cleaner according to claim 1. (3) The reinforcing bead has a substantially semicircular cross section concave on the contact side, and the movable terminal has a spherical protrusion having a radius larger than the radius of the reinforcing bead to form a contact point. A switch device for battery-powered vacuum cleaners.
