An electromagnetic relay includes an electromagnet device, an armature and a fixed terminal. By coil current through a coil, the electromagnet device generates first magnetic flux that forces the armature and the electromagnet device together or apart in a first end in a first direction of the armature. The armature is connected with a movable contact at a second end of the first direction and forces the movable contact and a fixed contact together or apart according to coil current. The fixed terminal is electrically connected with the fixed contact, and provided around the armature so as to cross the armature as seen from a second direction perpendicular to the first direction with the armature closing the fixed and movable contacts. Electric current through the fixed terminal generates a second magnetic flux in the armature, a direction of which is opposite to that of the first magnetic flux.

An inline reed relay comprises at least one reed assembly, at least one pair of metal pins, a housing and a control pin disposed on the housing. The reed assembly comprises at least two reed switches, each having two pins. The metal pins are respectively connected to the two pins of the reed switches. One end of each metal pin extends out of the housing. The inline reed relay allows the reed switches to be integrated through the injection molded housing, and the reed switches are connected to an external circuit board via the metal pins, because the metal pins can be maintained a fixed shape and difficult to deform. The processing size and position tolerances of the inline reed relay can meet the requirements of mechanized automatic welding, thereby improving welding efficiency and production assembly efficiency and reducing labor costs.

An electromagnetic relay includes an electromagnet, an armature configured to shift in response to a magnetic force generated by the electromagnet, a movable spring having a movable contact disposed thereon, a fixed spring including a first contact strip and a second contact strip, the first contact strip having a first fixed contact disposed thereon, the second contact strip having a second fixed contact disposed thereon, the first fixed contact and the second fixed contact facing the movable contact, and a linkage member configured to link the armature and the movable spring to shift the movable spring in conjunction with movement of the armature.

A household gas stove, comprising a gas burner, a gas valve for controlling a flow of combustion gas to the gas burner, an ignitor for igniting the combustion gas at the gas burner , and a knob mechanism for actuating the gas valve, wherein the knob mechanism comprises a movable magnet for generating a magnetic field and an immovable switch, wherein the switch is switchable from an off mode, in which the switch is outside a range of the magnetic field, into an on mode, in which the switch is within the range of the magnetic field, by means of moving the magnet relative to the switch, wherein the switch activates the ignitor when being switched from the off mode into the on mode.

In an embodiment a switching device includes at least two fixed contacts and one movable contact in a switching chamber and at least two auxiliary contacts, two spring contacts and a contact plate in the switching chamber, wherein each of the spring contacts contacts one of the auxiliary contacts with a first contact region and has a second contact region, wherein the contact plate is movable together with the movable contact, and wherein the contact plate is configured to contact the second contact regions of the spring contacts in a first switching state of the switching device and is configured to be arranged at a distance from the second contact regions of the spring contacts in a second switching state.
