Abstract: A terminal structure provided with a male terminal and a female terminal that includes with at least one set of elastic plate parts is disclosed. The male terminal is inserted between the elastic plate parts of the female terminal in a predetermined direction to cause each side surface of the male terminal to be pressed from each side of the elastic plate part due to the elastic force of the elastic plate parts, and the male terminal and the female terminal are electrically connected to each other.

Abstract: A stab assembly (41) in which a spring clip (24) and a conductor member (16) define a pair of engagement surfaces for engaging a stab blade (12). The conductor member (16) has an opening (34) to allow for the insertion of an extended surface of the spring clip (24). Once in position, the spring clip (24) and conductor member (16) are frictionally engaged and define a channel (126) that will accept and hold a stab blade (12). The stab assembly (14) is retained within a molded case circuit breaker (10) and provides electrical contact between a bus bar and the circuit breaker.

Abstract: A micromechanical electrostatic relay has a base substrate with a base electrode and a base contact piece. The relay also has an armature substrate with an armature spring tongue that curves away from the base substrate, and an armature electrode and an armature contact piece. When a control voltage is applied between the two electrodes, the spring tongue unrolls on the base substrate and thus closes the contact. The curvature of the spring tongue in the quiescent condition is produced by a coating with a compressive strain layer. In order to avoid undesired transverse arcs of the spring tongue, the compressive strain layer is subdivided into strips by slots in a longitudinal direction of the spring tongue. A tensile stress layer applied in surface-wide fashion over the strips and slots reinforces the compensation effect.

An enlongated rotatable contact member is positioned between the reverse-loop fingers and makes and breaks electrical contact with same upon being rotated. Operation is fast and positive and three-phase power can readily be accommodated. A viewing window can be provided for a rapid check of the position of the switch.

Abstract: A subminiature switch includes a housing having a base portion in the central part of which is implanted a common stationary contact comprising a rod-shaped conductor and having a common stationary terminal extending outside the housing. Implanted in the base portion on both sides of the common stationary contact are switching stationary contacts each comprising a rod-shaped conductor bent at two locations and having a switching stationary terminal extending outside the housing. The arrangement is such that the inter-terminal spacing outside the housing is greater than the inter-contact spacing inside the housing, thus making it possible to reduce the size of the switch housing and adapt the switch to various mounting structures.

Abstract: A low voltage switch having relatively long plunger travel that maximizes internal self-wiping of the contacts thereby to prolong switch life. The support for the internal contacts functions as a guide for the plunger as well as providing the necessary electrical spacing.

Abstract: A compact pushbutton switch comprises a housing in which three chambers are formed and connected by a common contact member. A fixed contact, a nonconducting member forming a continuation to the fixed contact, a slider movable along both the fixed contact and the nonconducting member, a movable contact fixed to the slider, a control pushbutton mounted to the slider, and a coiled spring are mounted in each of the chambers. The spring is made of an electrically conductive material, and interposed between the common contact member and the movable contact to bias the movable contact out of contact with the fixed contact. When no control pushbuttons are depressed, each spring acts to hold the movable contact out of electrical connection with the fixed contact. When any one of the pushbuttons is depressed, the corresponding spring serves to establish an electrical connection between the corresponding movable contact and fixed contact by its electrical conductive property.

Abstract: A contact arrangement for an isolating switch used as a ground connection of a switch system includes two switch pieces which are movable relative to one another, one of which is a knife and the other is a gripper. The gripper includes two contact pieces which are located opposite and parallel to one another and which engage the knife in the cutting-in state. Each contact piece is in turn formed by a plurality of adjacent contact elements. Such a contact arrangement is simple and economical to produce, while providing reliable contact-making for both high and low currents in spite of only slight static contact pressure. This result is achieved because the contact elements are U-shaped contact lamellae. Each lamella includes first and second legs connected via a curved part, the first leg being supported on the knife in the cutting-in state and the second leg being supported on current terminals formed on the contact pieces.

Means are provided on the switch means for making an electrical connection with the conductive member which was adapted to come into contact with the living tissue. Electrical connection between the switch means may be made through one of the springably releasable attachments or it may be made by means of a separate connector element.

The break contact arrangement is particularly well suited for pullout-type low-voltage and medium-voltage switchgear for connecting conductors of rectangular cross section.
