ABSTRACT:
An electromagnetic relay having a magnetic system actuatable to displace a movable contact element to make and break with at least one fixed contact element is provided with an insertable member of insulating material which has a vertical wall dividing the interior of the relay into essentially non-communicating portions respectively containing the contact elements and the magnetic system. The portion containing the magnetic system is further surrounded by opposed parallel lateral walls which, with the vertical wall, provide an insulating enclosure for the magnetic system. The magnetic system includes a yoke which has projections thereon slidably received in vertical grooves in the lateral walls. The lateral walls are sufficiently expandable such that during assembly the yoke can be inserted in the grooves in a snap-in manner. The yoke is attached to the magnetic coil so that no further structure is required to support the magnetic system.
