A terminal module (10) is provided with a case (22) and a terminal fitting (16) held in the case (22). The terminal fitting (16) includes a fixing portion (52) to be fixed to the case (22) and a leaf spring portion (54) cantilevered from the fixing portion (52) and deflectably and deformably accommodated in an empty space (20) of the case (22). A contact point portion (64) provided on a tip part (62) of the leaf spring portion (54) is displaced toward the fixing portion (52) and toward one side in a plate thickness direction by deflection and deformation of the leaf spring portion (54) when being pressed by a mating contact point (14).

A circuit interrupter includes a stationary contact and a moveable contact arm assembly having a moveable contact positioned thereon, the moveable contact configured to be moveable into and out of physical contact with the stationary contact. The circuit interrupter also includes an overcurrent tripping device coupled to the moveable contact arm assembly via a linkage assembly and configured to move the moveable contact out of physical contact with the stationary contact upon detection of an overcurrent situation. The moveable contact arm assembly is connected to the linkage assembly via at least two pivots positioned on the contact arm assembly, so as to cause a relative sliding action between the moveable and stationary contacts as the moveable and stationary contacts are moved into or out of contact with each other such that a wiping action is created in order to clean the moveable and stationary contacts.

The present invention relates to the field of heavy duty relays with electromagnetic, pneumatic or other mechanical means of actuation. In particular the invention relates to a relay or contactor which addresses the problem of contact welds formed during actuation of the relay. In one aspect the invention provides an electrical relay comprising a contact bridge portion carrying at least two spaced apart electrical contact surfaces, a terminal portion comprising at least two corresponding spaced apart electrical contact surfaces, and an actuating mechanism for selectively bringing the electrical contact surfaces of the bridge portion into electrical contact.

A rotary switch device includes a terminal base to which a center portion contact and a fixed contact member are fixed, a movable contact member, and a support portion. The movable contact member includes a contact protrusion part which is pressed in contact with the center portion contact at one end of the movable contact member and a first contact surface which is in contact with the fixed contact member at another end of the movable contact member, and which is operated to rotate around the center portion contact so as to short-circuit between the center portion contact and the fixed contact member at a conductive rotation position.

An electrical contact device has a housing with a vertical cavity and a horizontal cavity. A first contact element with a base that fits into the bottom of the vertical cavity of the housing, having a vertical primary protrusion from the end of the base, and having another vertical secondary protrusion from the other end of the base. The end of the secondary protrusion has a tertiary horizontal protrusion. The second contact element fits into the vertical cavity of the housing. The end of second contact element has a nub that inserts into a matching indentation under the tertiary protrusion of the first contact element, and acts as a retention feature. The other end of the second element is a vertical primary protrusion making contact with a device. A compliant element is positioned within the horizontal cavity of the housing and bracketed by the first contact element.

At the time of contact between the contacts, the first movable contact comes into contact with the first fixed contact before contact between the second movable contact and the second fixed contact is made. The first movable contact is located on a leading end side of the contact piece with respect to the second movable contact. The first divided piece includes a body and a projection. The body extends in the lengthwise direction. The projection projects in the widthwise direction of the first divided piece from the body. The projection includes a contact portion pressed by the link member.

A high-voltage direct-current relay includes two stationary contacts and a movable assembly, the movable assembly including a movable spring part, a main spring and a pushing rod assembly. The pushing rod assembly is composed of a pushing rod part and a U-shaped basket as two separate parts, the pushing rod part includes a fixing piece and a pushing rod fixed together with insulating plastic. The movable spring part and the U-shaped basket are mounted on the top of the pushing rod part, the two ends of the fixing piece are secured to the bottom of the side part of the U-shaped basket. The main spring is tightened between the bottom surface of the movable spring part and the insulating plastic of the pushing rod part, and the movable spring of the movable spring part is pressed to the inner side of the top part of the U-shaped basket.
