Title:
SWITCH BOX FOR WIRING AND MEMBER TO BE DETECTED
Document Type and Number:
Japanese Patent JP3493438
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To arbitrarily change magnetic force of a part to be detected and surely detect the approximate position of a switch box body and the center position of a drilled hole of wall material by laminating and housing a plurality of magnets in the part to be detected.
SOLUTION: With respect to a part to be detected 3 for showing the apprioximate position of a switch box 1 for piping or the center position of a drilled hole on a wall surface by magnetic detection, a plurality of magnets 6 are laminated and can be housed. In a case where wall material is normal thickness and the part to be detected 3 is at a position near a magnetic detector, the position of the switch box 1 can be detected from the wall surface by one magnet 6. On the other hand, in a case where the part to be detected 3 is distant from the magnetic detector at a prescribed distance or more, detection is difficult by one magnet 6 or the detection cannot be performed. In this case, the proper number of the magnets 6 is additively inserted and housed. Thereby magnet force is increased, and the switch box 1 and the center of the drilled hole of the wallmaterial can be detected surely.
