ABSTRACT:
An electromagnetic relay has a casing of electrically insulative material which is divided by an insulating partition into a coil space for receiving an electromagnet and a switching space for receiving a contact assembly. An armature is magnetically coupled to the electromagnet and is operatively connected to the contact assembly for switching contact operation thereof in response to energization of the electromagnet. The partition extends along the entire length of the electromagnet without leaving any communication path between the coil space and the switching space, such that the electromagnet in the coil space can be insulatively separated from the contact assembly in the switching space within the length of the electromagnet.
