Abstract: An electromagnetic relay includes an electromagnetic unit, a magnetic unit, first and second contacts, and a movable conductive terminal. The magnetic unit has a magnetic member having a fulcrum portion, a magnetic driven subunit, an arcuate groove, and an arcuate protrusion. The magnetic driven subunit includes a pushing block for pushing the movable conductive terminal, and a magnetic component magnetically attractable by the electromagnetic unit. The arcuate groove and the arcuate protrusion are respectively and interchangeably formed in the fulcrum portion and the magnetic component, and are pivotably connected to each other such that the magnetic component is pivotable about the fulcrum portion relative to the magnetic member. The movable conductive terminal is driven by the electromagnetic unit to contact one of the first contact and the second contact.

Abstract: An electromagnetic relay includes an electromagnetic unit, a magnetic moving subunit, a first conduct, a second conduct, a movable lead, and a movable contact. The movable lead has a swing portion and a resilient linkage portion. The movable contact is disposed on the swing portion. When the electromagnetic unit is energized, the magnetic moving subunit is attracted by the electromagnetic unit and pushes the resilient linkage portion of the movable lead such that the resilient linkage portion urges the swing portion to swing and that the movable contact disposed on the swing portion is urged to be in contact with one of the first contact and the second contact. When the electromagnetic unit is de-energized, the electromagnetic unit ceases to attract the magnetic moving subunit such that the movable contact is in contact with the other one of the first contact and the second contact.

Each of the clamping plates has a main portion extending from the base member, a clamping portion extending from the main portion in a direction away from the entrance hole, and a pressed portion extending from the clamping portion away from the base member. The receiving space has a quadrilateral cross section, is constricted in the direction and receives the lead. The clamping portions removably clamp the lead. Each clamping portion has a height less than that of the main portion.

Abstract: A pushbutton switch for a switch assembly includes a pushbutton unit and a resilient member. The pushbutton unit includes a mounting seat and a pushbutton that covers the mounting seat. The resilient member is disposed between the mounting seat and the pushbutton, and has an insert connected to the mounting seat and having opposite ends that are spaced apart in an extending direction, and two resilient arms extending respectively from the opposite ends of the insert. Each resilient arm has two contact end sections abutting against the pushbutton and spaced apart in a transverse direction, and is deformed when the pushbutton moves to a contact position so as to generate a restoring force which urges the pushbutton to a non-contact position.

The resilient member has a switch contactor, two resilient arms extending respectively from opposite ends of the switch contactor, two abutment segments engaging the limiting seat, and four sustainment segments extending away from the abutment segments and inclined toward the switch contactor. When the pushbutton is pressed to push the sustainment segments, the resilient arms are deformed to have a resilient force for urging the pushbutton away from the limiting seat, and to drive the switch contactor to contact and move an activator of a switch assembly.

The pushbutton unit includes a mounting seat for being in proximity to an activator of a switch assembly, and a pushbutton covering the mounting seat. The resilient member has a switch contactor adjacent to the activator, two resilient arms extending from the switch contactor, and two abutment segments connected respectively to the resilient arms and engaging the limiting seat. When the pushbutton is pressed to move toward the limiting seat, the resilient arms are resiliently deformed to have a resilient force for urging the pushbutton away from the limiting seat, and the switch contactor is driven by the pushbutton to contact and move the activator.

Abstract: A switch assembly includes a switch unit having first and second conductive plates, and a switch control unit having a sliding member and a locking member. The sliding member has a closed cycle guide groove, and the locking member has a locking portion to slide in the guide groove. When the locking portion is engaged in a first locking site of the guide groove, the first and second conductive plates are stabilized in their electrically disconnected state. When the locking portion is engaged in a second locking site of the guide groove, the first and second conductive plates are stabilized in their electrically connected state.

Abstract: An electromagnetic relay assembly includes a switching unit to push a sliding member and to place a locking portion of a locking member to lock the sliding member at a first position where the switching unit switches a first conductive plate and a second conductive plate to an electrically disconnected state. When a coil is energized, the sliding member is moved to a second position, and the locking portion of the locking member is placed to lock the sliding member in the second position where the switching unit is actuated by the sliding member to switch the first and second conductive plates to an electrically connected state.

Abstract: A USB3.0 connector includes an insulative body, a plurality of first and second terminals, and an outer shell covering the insulative body. The insulative body includes a base that has a base upper wall, a base lower wall, and two base sidewalls. The base lower wall has a rear end notched in a frontward direction to form a plurality of alternating shallow and deep notches to position first and second legs of the first and second terminals, which are bent downwardly. The alternating shallow and deep notches space the first legs apart from the second legs, respectively. The number of component parts for assembly is therefore reduced.

The engaging unit has a first engaging member provided on the terminal seat, and a resilient second engaging member provided on the housing and having an engaging hole for retaining the first engaging member therein and an inner surrounding surface that defines the engaging hole. The first engaging member is formed with a stop surface for abutting against the inner surrounding surface of the second engaging member to arrest separation of the terminal seat from the housing.

The contact projections and the inspection segments of the second terminals extend in opposite directions. A segment length of the soldering segments of the first terminals differs from that of the soldering segment of the third terminal.
