PROBLEM TO BE SOLVED: To improve a terminal support structure so as to enable to secure a required drawing intensity against an insulation board, by additionally forming a simple protrusion at a terminal side. SOLUTION: In the plug-in type electromagnetic relay, an electromagnet, a movable contactor, and a fixed contactor are loaded on the insulation board 9, through which terminals of each above component (for instance, a terminal conductor of the fixed contactor 4) are drawn out toward a rear-face side of the board and plugged into a socket for use. For the terminals fixed and supported to an assembly position by being pressed into square holes 9a opened in the insulation board, press-in protrusions 4b biting into inner faces of the square holes of the insulation board for engagement are formed at their side edge, and at the same time, second protrusions 9c are formed on a board face at a position engaged with open edges of the square holes in exposure at a rear-face side of the insulation board in an assembled state with the terminals pressed into the square holes. The second protrusion is to be a trapezoid with a tapered face formed toward a tip side of the terminal. COPYRIGHT: (C)2007,JPO&INPIT
