A switch device includes, a movable terminal including a snap action mechanism that bends a spring when a user moves an operating portion, a first fixed terminal that contacts the movable terminal when the spring is not bent, a second fixed terminal that contacts the movable terminal when the operating portion is moved by a specified amount to bend the spring, a case including an opening, and a cover that closes the opening and is separate from the first fixed terminal. When the opening is closed by the cover, the first fixed terminal is positioned in the case by the cover.

A switch device includes a movable terminal including a snap action mechanism that bends a spring when a user moves an operating portion, a first fixed terminal that contacts the movable terminal when the spring is not bent, a second fixed terminal that contacts the movable terminal when the operating portion is moved by a specified amount to bend the spring, and a housing that accommodates at least the first fixed terminal. The first fixed terminal includes a first fixed terminal body that contacts the movable terminal, and a first fixed terminal connection pin bent sideward from the first fixed terminal body and mounted on a board. The housing includes a groove portion that allows for passage of the first fixed terminal connection pin.

A disconnecting switchgear has three mutually exclusive positions II-0-I, with position II energizing the load circuit, position 0 de-energizing the load circuit and position I grounding the circuit, which reduces the electrical risk when interacting with an electrical panel. The switchgear includes a control interconnected with a body, where the control includes a gripping mechanism with an electrical labelling element, an extension mechanism, a locking mechanism and indicator labels; the body includes a group of external electrical conductors or connection terminals, a group of internal electrical conductors or poles, an earth short-circuit electrical conductor, displays of electrical quantities, luminous indicators, and sight glasses for viewing moving poles; electrical conductors and electrical contacts interconnected with a drive shaft and the latter to a power-transmission mechanism.

An electric switch including a frame, a first stationary contact, a roll element adapted to rotate relative to the frame, a rotating contact stationary fixed to the roll element, and an arc extinguisher plate system. The arc extinguisher plate system includes at least one first arc extinguisher plate for extinguishing an electric arc generated during an opening event between the first stationary contact and a first contact portion of the rotating contact. The at least one first arc extinguisher plate is fixed to the roll element.
