Electromagnetic relay

An electromagnetic relay comprising:

• a casing of electrically insulative material having a bottom wall having lateral sides, opposed side walls having longitudinal ends, said side walls extending upwardly from the lateral sides thereof, an end wall extending upwardly from one of said longitudinal ends of the bottom wall and joining said side walls at its lateral ends;
• an insulation partition extending from said end wall in generally parallel relation to the bottom wall between the opposed side walls so as to define a coil space thereabove and a switching space therebelow;
• said bottom wall, side walls, end wall and insulation partition being integrally formed of insulative material;
• an electromagnet having a length defined by two longitudinal ends, said electromagnet being received within said coil space and having a winding with a longitudinal axis extending horizontally along said partition;
• a contact assembly received within said switching space with its switching contact portion located in close proximity to said end wall and including at least one movable contact;
• an armature which is disposed adjacent the longitudinal end of the electromagnet remote from said end wall to be magnetically coupled thereto and which is operatively connected to said contact assembly for switching operation thereof in response to the energization of the electromagnet;
• said partition extending along the entire length of the electromagnet without leaving any communication path between the coil space and the switching space so as to completely separate the coil space from the switching space along the length of the electromagnet;
• said partition terminating at an edge, which edge is recessed with respect to the longitudinal ends of the side walls remote from the end wall to define thereat a recess through which the coil space and the switching space are intercommunicated;
• and
• said armature having a card of electrically insulative material which extends through said recess into the switching space where it is connected to the movable contact of the contact assembly.
