| 摘要 | PURPOSE: To prevent water from being exposed at the portion where a current flows even when a power switch is kept off in the magnetically operated power switch provided with an electric contact piece and a magnetically attracting member in the sealed first chamber and provided with a magnet member and an operating member in the adjacent second chamber. CONSTITUTION: This magnetic switch 20 is composed of a two-chamber housing 22 formed with a sealed lower chamber 24 and an adjacent opened upper chamber 26. A magnet 82 is revolved around pins 98, 100 between the closure position and open position. The magnet 82 is normally held at the open position by a deviation spring 110 provided between the rear face of the magnet 82 and the cross sectional wall of the upper chamber 26. When the extension section 120 of a slide cap and a cam 122 are moved, the cam 122 is retained in the recess 120, the magnet 82 is revolved apart from a separating wall 28 by a lift spring 110, and the switch 20 is opened. The magnetic force between the magnet 82 and metal plates 44, 46 surmounts the deviations of plate springs 34, 36 to attract the metal plates 44, 46 upward, moving electric contact pieces 34, 36 are brought into electric contact with static contact pieces, and the magnetic switch 20 is set to the closure position. | ||||||
