摘要: Provided is a switch device with high operation reliability in which an opening-closing contact portion is not erroneously opened or closed even when an external impact is applied. A switch unit, which is configured to be separable from an operation unit, is provided with a rotary drive plate, which rotates between a standby position and a usage position, drives an opening-closing contact mechanism of the switch unit in the standby position to assume an opening-closing state at the time the operation unit is at an operation position, and drives the opening-closing contact mechanism in the usage position to assume an opening-closing state at the time the operation unit is at a standby position. The operation unit is provided with an engagement portion that is engaged with the rotary drive plate when the operation unit is joined and attached to the switch unit and rotary-drives the rotary drive plate from the standby position to the usage position. The opening-closing contact mechanism is set to a predetermined opening-closing state by detaching/attaching the operation unit from/to the switch unit.

摘要: There is provided an electromagnetic contactor with which it is possible to suppress electromagnetic repulsion forces which cause a movable contact to open when current is conducted without any effect of magnetic fields of external connection conductors. The electromagnetic contactor includes a contact mechanism (CM) including a pair of fixed contacts (2), interposed in a current conduction path, which have their respective fixed contact portions (2a), (2b) and a movable contact 3 having a pair of movable contact portions (3b), (3c) which are able to come into and out of contact with the pair of fixed contact portions, wherein at least one of the pair of fixed contacts or movable contact is formed in a shape such as to form magnetic fields which generate Lorentz forces opposing electromagnetic repulsion forces generated in an opening direction between the fixed contact portions and movable contact portions when current is conducted. Also, the attachment direction of fixed portions (22), (23), each of which, having an external connection conductor (20), (21) connected to an external connection terminal (2i), (2j) of the corresponding fixed contact 2, is attached to the external connection terminal of the external connection conductor, is set so as to cross the direction of current flowing through the movable contact.
