The invention relates to a self-supported activation device for an electromechanical switch, which can be used for the isolation of a faulty element of a battery, comprising a set of electrically connected elements. The activation device (1) is intended to activate switching in a switching device (2) of the type having electrical contact means (3) that can move between first and second electrical positions. The activation device comprises a current sensor (6a, 6b), a retaining element (7), and at least two movable elements (8, 9) solidly connected to a coil (10). When a current is detected by the current sensor (6a, 6b) the activation device can move from a non-activation configuration, in which the movable elements are retained by the retaining element in a first position intended to prevent the movement of the contact means of a switching device, into an activation configuration, in which the movable elements are no longer retained in the first position by the retaining element and instead occupy a second position intended to allow the movement of the contact means of a switching device. The coil (10) comprises a passage space for at least part of the contact means, and each of the movable elements can rotate about an axis such as to clear the passage space, in the aforementioned second position, while remaining solidly connected to the coil.

A switch is provided with: a base; a fixed contact member that has a fixed contact; a movable contact member that has a movable contact, moves in a first direction to bring the movable contact into contact with the fixed contact, and moves in a second direction opposite to the first direction to separate the movable contact from the fixed contact; an elastic body that energizes the movable contact member in the second direction; and a cover that covers the fixed contact member and the movable contact member. An operation body is configured to move the movable contact member sequentially to a first position to which the movable contact member is moved from an initial position in the first direction to bring the contacts into contact with each other, a second position to which the movable contact member is moved from the first position in the second direction while the contacts are kept in contact, and a third position at which the movable contact member is moved again in the first direction from the second position, the third position located between the first position and the second position.

A robotic arm of an automated pipetting system has a pipetting tip adapter and a slide switch to detect the presence of pipetting tips on the pipetting tip adapter is disclosed. The slide switch has first support member and second support member configured to slide relative to one another between first and second positions along a movement axis, an electrically conducting contact pad arranged on the first support member, an electrically conducting terminal physically attached to second support member in physical contact with the contact pad when support members are in first position, where the terminal is a first resilient wiping member expanding along the movement axis, first wiping member is not in physical contact with the contact pad when support members are in second position, and an electric current can flow between first wiping member and the contact pad when support members are in first position.

An electrical switch assembly includes a contact element to be moved towards a further contact element for generating an electrical connection; and a drive for moving the contact element; wherein the drive includes a plunger with a connection member interconnected with the contact element; wherein the plunger includes a mechanical structure with a top side to which the connection member is connection, and a bottom side opposite to the top side; wherein the drive includes a Thomas coil for moving the plunger via an electrically conducting top face, which is provided on the top side and an electrically conducting bottom face, which is provided on the bottom side. The mechanical structure includes at least one channel between the top side and the bottom side, the at least one channel extending transverse to a movement direction of the plunger. Furthermore, the mechanical structure fills less than 50% of a volume between the top side and the bottom side.

A switching system, in particular of an on-board electrical system of a motor vehicle having a first disc which has a first, a second, a third, and a fourth stationary contact. The second and the third stationary contact, are electrically contacted by a first contact bar of the first disc. The switching system also has a second disc which has a first, a second, a third, and a fourth movable contact. The first and the second movable contact are electrically contacted by a second contact bar of the second disc, and the third and the fourth movable contact are electrically contacted by a third contact bar of the second disc. The second disc is rotationally mounted about a rotational axis relative to the first disc, wherein all the contacts are electrically connected in series in an angular position. A circuit breaker is also provided that includes a switching system.

A rocker switch device is provided in which a pair of shaft portions are projectingly provided on mutually opposing faces of extremity portions of a pair of side wall parts of a switch case, the pair of shaft portions being aligned on the same axis as each other, a bearing hole is formed in an operating knob so as to extend therethrough, the pair of shaft portions being rotatably fitted into the bearing hole, a projecting portion is provided on an outside face of the pair of side wall parts, the projecting portion being pressed into contact with the support body to thus prevent rattling of the switch case, and a support pin is fitted into the bearing hole, opposite ends of the support pin abutting against extremities of the pair of shaft portions respectively. Such arrangement prevents switch malfunctioning, and restrains deformation of the side wall parts.

This invention can be used as mini-micro-switching, up to macro switching. An electronic module having several input copper circuit traces, and several output copper traces, or wires, with some traces having disconnects, consisting of drilled holes, which can be bridged by conductive fasteners. This invention is also solving switching of differing functions both in the industry, and after that the product is in the market and the customer requests switching options. Selecting a switching options can be accomplished on a module, by first remove a conductive fastener from one position and attach the fastener in a second position on copper traces. Where the fastener is removed and not re-inserted, an open circuit trace occurs. Thereby accomplishing: selecting, reversing, or switching of one, or of a multiple of circuits.

A three-position disconnector switch includes an earthing contact, a power out contact, a power in contact, a piston, and a threaded rod. A length of the piston is such that in a first switch position an outer surface of a wall of the piston makes an electrical contact between the power out contact and the power in contact. The length of the piston is such that in a second switch position the outer surface of the wall of the piston does not make an electrical contact with either the earthing contact or the power in contact. The length of the piston is such that in a third switch position the outer surface of wall of the piston makes an electrical contact between the earthing contact and the power out contact. The piston includes an inner threaded section configured to engage with the threaded rod.
