摘要： A relay for assembling in terminal blocks includes an electromagnetic drive arrangement including an armature, an armature bearing spring, and a yoke. The armature is at least partially spaced from the yoke, is movably mounted, and is reduces the distance between the yoke and the armature under an effect of an electromagnetic force. The armature bearing spring applies a spring force counteracting the electromagnetic force. The yoke interacts electromagnetically with the armature to apply the electromagnetic force. A contact spring has a first contact surface and a contact arm, and the contact arm is spaced from the first contact surface and comes into contact with the first contact surface via a pressure force acting to establish an electrical connection between the first contact surface and the contact arm. An insulating element electrically isolates the armature from the contact arm and actuates the contact arm to produce the pressure force.

摘要： A latching relay includes first and second coils and a common plunger operatively connected therebetween such that activation of the first coil moves the plunger in a first direction and activation of the second coil moves the plunger in a second direction, opposite the first direction, the first and second directions lying in a first plane. A limit switch includes a common contact and first and second coil contacts, where a position of the common contact is alternately switched between electrical connection to either the first or second coil contact based on a position of the plunger. A slide toggle accessible by a user is operatively connected to the plunger and slideable together with the plunger such that actuation of the slide toggle by the user causes manual actuation of the plunger. The slide toggle is slideable in a second plane parallel to the first plane.

摘要： 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).
