ABSTRACT:
An electromagnetic relay having a high contact rating having an armature and yoke movable by the magnetic coil is provided with an insertable internal member having a vertical wall which divides the interior of the relay into a first portion containing the magnetic coil, armature and yoke, and a second portion containing the contact elements and a slidable member for transmitting movement. The insertable member has a second vertical wall perpendicular to the dividing wall which is provided with a slot for receiving the slidable member to permit movement of the member between the two portions of the relay interior. In order to further increase the insulation between the yoke and a stationary contact member, the stationary contact member is provided with a trapezoidal recess which receives a correspondingly shaped projection of the dividing wall which is interposed between the stationary contact element and the slidable member.
