ABSTRACT:
An electromagnetic contactor comprising a terminal and contact block supported at one end on a magnetic frame includes cooperating interlocking means on its coil bobbin and the block for rigidly supporting the block at an additional location. The interlocking means on the coil bobbin include a pair of oppositely directed support arms with upstanding projections in mating engagement with wall members of the block. Each support arm also has a recess that receives a sheet metal coil terminal with lugs that are bent into contact with the arm after insertion of the terminal into the recess to prevent movement of the coil terminal with respect to the arm.
