Abstract (en)
In an electromagnetic switch device incorporated with fuse terminals (31, 32, 36, 37) for at least one fuse (41), a terminal holder (12) retaining fuse terminals therein is fit onto an open end of a switch casing (11) that receives an electromagnetic coil (13) and associated component parts, and the terminal holder includes a peripheral wall (12A) that opposes a side wall of the switch casing in an overlapping relationship and defining a small gap (51) therebetween. At least one of the terminal pieces includes a heat dissipating extension (34A, 35A) extending into the gap between the peripheral wall of the terminal holder and opposing side wall of the switch casing. The heat dissipating extension promotes the dissipation of the heat conducted through the corresponding terminal piece to the ambient air. The improved heat dissipation contributes to the improvement in the electric properties of the electromagnetic switch device, and ensures a high reliability.
