| 摘要 | An aspect of the present invention provides an electric magnet device (41), in which a smooth movement of an armature (71, 87) is ensured and, even if a vibration or an impact is applied, an attraction state between a yoke (50, 85, 91) and the armature (71, 87) is maintained to prevent a malfunction, and a switch (1) provided therewith, where the electric magnet device (41) includes: a coil (48) adapted to insert through an armature (71, 87) and a yoke (50, 85, 91) so as to attract surfaces of the yoke (50, 85, 91) and the armature (71, 87), which are opposed to each other, to receive a voltage, to excite for separating the surfaces of the yoke (50, 85, 91) and the armature (71, 87); the armature (71, 87) disposed on one end side of the coil (48); and the yoke (50, 85, 91) disposed on the other end side of the coil (48) and adapted to oscillate, such that an oscillation angle of the yoke (50, 85, 91) is greater than that of the armature (71, 87). | ||||||
