Electromagnetic relay

An electromagnetic relay comprising in combination,

• an insulating base member,
• an electromagnetic coil mounted on said base member,
• an armature means pivotally mounted to said base member with one end portion movable between upper and lower positions in response to the energization and denergization of said coil,
• spring means biasing said armature into one of said positions,
• a contact carrier post affixed to said one end portion of said armature and extending upwardly therefrom,
• first and second contacts mounted to said base on opposite sides of said armature,
• a lower contact carrier blade slidably mounted on said post and carrying a pair of contacts adapted to respectively engage said first and second contacts when said armature is in said lower position.
• first and second upstanding abutment guide means integral with said base member and respectively disposed on opposite sides of said armature for limiting lateral movement thereof and for limiting rotational movement of said lower contact carrier blade,
• first and second contact carrier brackets mounted to said base and respectively carrying third and fourth contacts in spaced, vertical alignment with said first and second contacts,
• an upper contact carrier blade slidably mounted on said post and carrying a pair of upper contacts adapted to respectively engage said third and fourth contacts when said armature is in said upper position, and
• a compression spring compressed between said upper and lower contact carrier blades to urge said blades in mutually spaced apart relationship.
