摘要： A contact mechanism has a base, a pair of fixed contact terminals provided side by side on the base, a first contact mechanism including a first fixed contact provided in one of the pair of fixed contact terminals, and a first movable contact that contactably and separably faces the first fixed contact, a second contact mechanism including a second fixed contact provided in another of the pair of fixed contact terminals, and a second movable contact that contactably and separably faces the second fixed contact, and a magnetic field generation unit having a permanent magnet disposed between the first contact mechanism and the second contact mechanism such that magnetic fields in opposite directions are generated respectively between contacts of the first contact mechanism and between contacts of the second contact mechanism when currents in opposite directions flow in the first contact mechanism and the second contact mechanism.

摘要： An electromagnetic relay has a base, an electromagnet unit mounted on the base, and having a coil, a movable contact plate having a movable contact mounted on a distal end thereof, and a first stationary contact terminal and a second stationary contact terminal. The movable contact plate is moved by electrically energizing and deenergizing the coil of the electromagnet unit to cause the movable contact to make and break contacts with the first stationary contact terminal and the second stationary contact terminal alternately. The first stationary contact terminal and the second stationary contact terminal are implanted vertically in the base. The first stationary contact terminal supports a stationary contact. The second stationary contact terminal supports an insulating member mounted thereon.

摘要： A control circuit for a switch device including a first switch element including a movable contact and a drive coil that controls the movable contact of the first switch element, the control circuit for returning the movable contact when the drive coil turns off the movable contact after the drive coil turns on the movable contact during supply of a source voltage from a power source, the control circuit includes a second switch element inserted between a rectifier circuit or a surge absorbing element and the first switch element, the second switch element being turned off when the supply of the source voltage is turned off. The rectifier circuit or the surge absorbing element is connected between the power source and the control circuit. The first switch element is turned off the movable contact is returned by turning off the second switch element to turn off the first switch element.
