Magnetic latching relay
A magnetic latching relay includes a base, a magnetic circuit portion, a pushing card and a contact portion; the base is provided with a first blocking wall to divide the base into an upper cavity and a lower cavity, the magnetic circuit portion and the contact portion are installed in the upper cavity and the lower cavity respectively; an iron core, two yokes and a magnetic steel of the magnetic circuit portion are formed an E-shaped magnetic conductive structure with a 90 degrees side turn; the middle position of an armature is rotatably supported above the magnetic steel, two ends of the armature respectively correspond to the tops of the two yokes; an upper end of the pushing card is connected to one end of the armature, and a lower end of the pushing card is connected to a free end of a movable spring of the contact portion.
Electromagnetic relay
An electromagnetic relay includes a casing, a coil set, a rotating bridge, first and second extension arm, first and second switch conductive plate assemblies, and first and second gripper modules. The novel design of the rotating bridge allows the first and second switch conductive plate assemblies to have synchronous contact or disconnection and provide sufficient and appropriate force to a first movable contact and a first fixed contact of the first switch conductive plate assembly and a second movable contact and a second fixed contact of the second switch conductive plate assembly to achieve a stable conduction and ensure a reliable separation for a disconnection, so as to achieve the effects of reducing the excessive change of resistance during operation, preventing high temperature caused by incomplete contacts, and improve application performance.
Trip free relay
An overload relay is disclosed in which a single operator coil is controlled for both tripping and resetting. A permanent magnet and a spring make the device bi-stable, so the coil may be unpowered when in the trip and reset states. Energization of the coil overcomes the magnet to allow tripping, while energization in an opposite direction adds to the magnet force to reset the device. An electromagnetic activation path overrides a mechanical activation path for electromagnetic tripping despite attempted manual resetting. The device may be pulse width modulated to reduce power consumption.
Switch and associated methods
The present invention is related to a switching device having a contactor and an actuator. The contactor has at least a first contactor member and a second contactor member. The actuator is configured to actuate the contactor. At least one of the contactor members has a varying or variable thickness along its length such that the at least one of the contactor members has a relatively thick portion and a relatively thin portion.
SWITCHING DEVICE FOR GUIDING AND SWITCHING OF LOAD CURRENTS
A switching device for guiding and switching of load currents includes: a movable switching component having a first movable contact and a second movable contact; a first fixed contact and a second fixed contact; a supporting device for supporting the switching component; and a magnetic actuator. The first movable contact is in contact with the first fixed contact and the second movable contact is in contact with the second fixed contact in a switched-on state of the switching component. The first movable contact is electrically separated from the first fixed contact and the second movable contact is electrically separated from the second fixed contact in a switched-off state of the switching component. The switching component is arranged such that the switching component moves between the switched-on state and the switched-off state by at least a rotational movement of the switching component and a translational movement of the supporting device.

ELECTRIC SWITCH
The invention relates to an electric switch that serves to switch on and/or off electric devices and for this purpose has a contact system in the switch housing. By means of a manual actuating element or a remotely controlled actuator, a switching operation can be effected.
RELAY
A relay includes an electromagnetic drive unit with a rotatable armature and a yoke. The rotatable armature includes a first magnetic contact region and the yoke includes a second magnetic contact region. The first magnetic contact region is in touch with the second magnetic contact region in a first state of the relay. The relay further includes at least one immovable first electric contact and a moveable contact arm with at least one second electric contact.

Electromagnetic relay
The invention relates to an electromagnetic relay (1), more particularly a safety relay (1). This has a main body (10) and a coil system (20, 120) located thereon, the coil system (20, 120) having a coil (24, 124) and a yoke (25, 125) which extends through the coil (24, 124) along a winding axis (WA) of the coil (24, 124). An armature (30, 130) for the relay (1) is located next to the coil (24, 124) and mounted such that it can pivot about an armature bearing axis (AA, AA) and has pole shoes (33a, 33b, 33c, 33d, 133a, 133b) for magnetically coupling with the yoke (25, 125) of the coil system (20, 120). The relay (1) also comprises a contact system (50) having at least two contact springs (51, 53), wherein each spring movement plane (FB) of the contact springs (51, 53) extends across the winding axis (WA) of the coil (24, 124), preferably at a substantially right angle. At least two actuators (36, 37, 41, 42) are located on the armature (30, 130), which actuators (36, 37, 41,42) are allocated to the contact springs (51, 53) in order to actuate same and which actuators (36, 37, 41, 42) extend radially outwards on the armature (30, 130) with respect to the armature bearing axis (AA, AA) in a longitudinal direction (AL) of the armature (30, 130), wherein the radially outermost ends of the two actuators (36, 37, 41, 42) are farther away from the armature bearing axis (AA, AA) than the pole shoes (33a, 33b, 33c, 33d, 133a, 133b) of the armature (30,130).
