FIG. 1 shows a reed switch sealing assembly for a proximity switch according to an embodiment of the present invention, which is sealed and molded so that the detection surface is located outside the reclosing area of the normally closed reed switch sealing assembly. FIG. 3 is a front sectional view of a reed switch sealing assembly of a proximity switch. FIG. 2 is a front sectional view illustrating the positional relationship between a conventional proximity switch and its operating state. FIG. 3 is a plan view showing the positional relationship between the detection magnet part of the proximity switch and the reed switch part. FIG. 4 is an operating characteristic diagram showing the operating state of the reed switch of the normally closed magnetic type proximity switch having the positional relationship shown in FIG. 3, with the position of the detected magnet portion as a variable. 1... Reed switch, 2... Bias magnet,
3... Reed switch sealing assembly, 4... Magnet section for detection, 5... Stopper, 6... Sensing surface.
