Provided herein are coil support structures and methods of retaining a printed circuit board assembly (PCBA) of a relay. In some embodiments, a bi-stable relay assembly may include a coil support structure, having a central section extending between a first end section and a second end section, and set of biasable fasteners extending from the first end section and the second end section, wherein each of the set of biasable fasteners includes a sloped engagement surface and a retention slot. The coil support structure may further include a PCBA coupled to the first and second end sections of the coil support structure, wherein the coil support structure extends within the retention slot of each of the set of biasable fasteners.

An auxiliary contact unit to be attached on a side surface of an electromagnetic contactor by a snap-fit, wherein the snap-fit includes: a projecting piece projecting toward the electromagnetic contactor and having a tip end portion engaging with the electromagnetic contactor, the tip end portion being formed in a hook shape; and a release operating portion formed on a base end side of the projecting piece and configured to, by bending when pressed from an outside, cause the tip end portion engaged with the electromagnetic contactor to be released.

A relay includes an armature, a yoke configured to be electromagnetically coupled to the armature, and a bracket-shaped clamping spring. The armature lies at least partially flat on the yoke, and a receiving depression is partly formed in the armature. The bracket-shaped clamping spring surrounds the armature and the yoke on an end face such that the armature is fixed on the yoke. The bracket-shaped clamping spring has a first clamping limb arranged in the receiving depression of the armature, and a second clamping limb lying on the yoke. The first clamping limb has an angled tab which engages elastically into a recess formed in the receiving depression of the armature.

The present invention refers to a switch device with at least one contact point, the contact point having a first contact and a second contact, the first and second contacts being spaced apart from one another in an open position and electrically contacting one another in a closed position, the contact point being assigned an arc blowout device for generating a magnetic blowing field, the blowout field being such that an arc produced when the contact point is opened is blown away from the contact point. In accordance with the invention, at least one of the two contacts is provided with a non-conductive cover on a non-contact-facing side which faces away from the other contact, which cover prevents a base point of the arc from crossing the non-contact-facing side.

An electromagnetic relay includes a first movable contact piece, a moving member, a coil, and a movable iron core. The moving member holds the first movable contact piece. The movable iron core is connected to the moving member and is configured to move by a magnetic force generated by the coil. The moving member is made of resin having electrical insulation. The moving member includes a first member and a second member. The second member is connected to the first member by snap fitting. The first member includes a first protrusion. The second member includes a second main body, a first locking portion, and a first arm. The first locking portion locks to the first protrusion. The first arm connects the second main body and the first locking portion. A thickness of the first arm is smaller than a thickness of the first locking portion.

An electromagnetic relay including: a base unit that includes a slit having a first wall part and a second wall part, and a first projection projecting from the first wall part of the slit; a terminal that is press-fitted into the slit, and includes a second projection at a position opposite to the first projection; and a preventer that prevents deviation of the second projection against the first projection when the terminal is press-fitted into the slit.

The present invention refers to a switch device with at least one contact point, the contact point having a first contact and a second contact, the first and second contacts being spaced apart from one another in an open position and electrically contacting one another in a closed position, the contact point being assigned an arc blowout device for generating a magnetic blowing field, the blowout field being such that an arc produced when the contact point is opened is blown away from the contact point. In accordance with the invention, at least one of the two contacts is provided with a non-conductive cover on a non-contact-facing side which faces away from the other contact, which cover prevents a base point of the arc from crossing the non-contact-facing side.

A relay coil assembly includes a bobbin having flanges on two ends, an enameled wire wound around bobbin, a coil pin mounted to the flange and having an insertion portion, an enameled wire fixing portion and a signal wire fixing portion, and a signal wire. The signal wire fixing portion is provided with a first engagement recess with an opening facing downward, in which the signal wire is engaged. An inverted hook is provided at one of two recess sidewalls of the first engagement recess, and a slope section is provided at one of the two recess sidewalls of the first engagement recess. The opening gradually enlarges from inside to outside along the slope section, which is capable of squeezing the signal wire into the first engagement recess and the inverted hook is capable of preventing the signal wire from coming out.

The present utility model provides a contactor, comprising: a housing, including a first side plate and a second side plate disposed opposite to each other; a static iron core and a movable iron core located inside the housing, a coil bobbin fitted on the static iron core, a coil wound on the coil bobbin, an elastic device located between the coil bobbin and the movable iron core, and a moving contact and astatic contact disposed opposite to each other, wherein the coil bobbin includes a contact end surface facing the movable iron core and a first fixing part and a second fixing part fixed to edges of the contact end surface, length directions of the first fixing part and the second fixing part are parallel to the first side plate and the second side plate, the first fixing part is in contact with and connected to the first side plate, and the second fixing part is in contact with and connected to the second side plate. The contactor according to the present utility model has a narrower width and saves installation space.

An electromagnetic relay includes a first movable contact piece, a first movable contact, a second movable contact, a moving member, a coil, and a movable iron core. The moving member holds the first movable contact piece. The moving member is made of a resin having electrical insulation. The moving member includes a first member and a second member. The first member is connected to a movable iron core. The second member is a separate body from the first member. The second member is connected to the first member by snap fitting. The first member includes a convex portion. The convex portion projects toward the second member in a moving direction of the moving member. The second member includes an inspection hole.
