Electromagnetic relay for mounting on circuit board - has U-shaped magnetic circuit and has armature inside coil former

摘要

The relay has an armature inside the coil former surrounded by the magnetic circuit (3) which serves as a frame. Its two parts (4, 5) are parallel to the armature (6) and are bent upwards so that the magnetic circuit (3) is U-shaped. Around the armature (6) is a coil former (2) retained by a leaf spring (7) retained in position by small screws (8). The base frame connections of the relay are made by welding, and the contact springs are supported on insulated carrier blocks (16) held down by screws with countersink heads (15). Locking of the assembly against rotation is achieved by fixing pins (21, 22).
