PROBLEM TO BE SOLVED: To effectively restrict the conditions of an external magnetic field for operation in an operating conditions restriction type switch using a switch with a reed piece.;SOLUTION: A first switch part 21 and a second switch part 22 are connected to each other in series on a base 23 via a connecting member 25, which is electrically a conductor and magnetically a non-magnetic material, and the whole body is covered with a cover 26. Only when a permanent magnet approaches the switch part 21 and another permanent magnet simultaneously approaches the second switch part 22, this device operates and is turned on.;COPYRIGHT: (C)2003,JPO
