摘要： The pressing member is configured to move to an off-position and an on-position. When the pressing member is located at the off-position, the first contact and the second contact come into a non-contact state. When the pressing member is located at the on-position, the first contact and the second contact come into a contact state by press of the pressing member against the contact piece. The actuator moves the pressing member from the off-position to the on-position via an overshoot position located beyond the on-position. The contact piece includes a body, and a low rigidity portion having rigidity lower than rigidity of the body. The pressing member presses the low rigidity portion.

摘要： Electromagnetic actuators capable of generating a symmetrical bidirectional force are disclosed. The electromagnetic actuators include a housing made of a ferromagnetic material and a shaft made of a magnetically inert material movable along an axis within the housing. In one type of actuator, captive permanent magnets are arranged on opposite interior end walls of the housing and an electromagnetic coil is mounted on a central portion of the shaft. The electromagnetic coil is capable of generating a force when energized that causes linear displacement of the shaft in either direction along its axis depending on the direction of current through the electromagnetic coil. In another type of actuator, captive electromagnetic coils are arranged on opposing inner end walls of the housing, and a permanent magnet is mounted on a central portion of the shaft. The electromagnetic coils are capable of generating a force when energized that causes linear displacement of the shaft in either direction along its axis depending on a direction of current through the electromagnetic coils.

摘要： A carrier sub-assembly for an electrical relay device includes a plunger and a shaft. The plunger is formed of a ferromagnetic material. The plunger has a generally cylindrical shape extending between a top side and a bottom side of the plunger. The shaft extends between a contact end and an opposite plunger end. The shaft is directly secured to the plunger without a discrete component between the shaft and the plunger securing the shaft to the plunger. The shaft and the plunger are configured to move together within the electrical relay device. A segment of the shaft including the contact end protrudes from the top side of the plunger for securing to a movable contact of the electrical relay device.

摘要： A low-profile electrical contactor is provided comprising at least one electrical contact switch, an actuation means and a current determining device. The or each electrical contact switch has first and second electrical terminals, an electrically-conductive busbar in electrical communication with the first electrical terminal, the busbar having two end faces between which a current can flow in a flow direction and at least two flat sides in parallel with the flow direction, at least one fixed electrical contact which is attached to the busbar, an electrically-conductive moveable arm in electrical communication with the second electrical terminal, and at least one moveable electrical contact which is attached to the electrically-conductive moveable arm to form an electrical contact set with the fixed electrical contact. The actuation means can actuate the electrically-conductive moveable arm of the or each electrical contact switch between open and closed conditions. The current determining device has a first field-modifying element formed of a magnetic material located at or adjacent to the first end face of the busbar, a second field-modifying element formed of a magnetic material and located at or adjacent to the second end face of the busbar, at least one sensing coil at or adjacent to the busbar and the first and second field-modifying elements, and having a coil axis between planes of the first and second flat sides.

摘要： A contact-breaker for a heat engine starter comprises a cap, a micro-solenoid having a coil which is stationary relative to the cap, and a core which is translational relative to the cap between a starting position and an end position. At least two contact terminals are stationary relative to the cap. A contact plate is inside the cap and is movable between a deactivated position in which the contact plate is spaced from the contact terminals and an active position in which the contact plate is in contact with the contact terminals. The contact-breaker is characterized in that the contact plate is secured to the core of the micro-solenoid in such a way that the contact plate drives the core of the micro-solenoid towards the starting position of the core when the contact plate moves from the active position into the deactivated position.

摘要： A switch structure including a first electrode, a second electrode, a first moving member disposed next to the first electrode along a first axis and having a first tenon unit, and a second moving member disposed at an end of the first moving member and facing the first electrode is provided. The second moving member movably disposed next to the first moving member has a second tenon unit. The first axis is orthogonal to the second axis. When the first moving member moves to a first position and the second moving member moves to a second position, the first and the second tenon units are interfered with each other, and the first electrode is electrically connected to the second electrode. When the second moving member moves to a third position, the first moving member moves along the first axis and passes by the second moving member.
