摘要： A switch includes a first contact and a second contact that are placed along an operating shaft and can reciprocate with respect to each other. An end of the second contact opposite to an end thereof on the side of the first contact is housed in a housing space of a housing box. The pressure in the housing space is increased due to an arc generated when the first contact approaches the second contact. The increased in the pressure causes the second contact to move toward the first contact.

摘要： A switchgear includes a movable part capable of reciprocating movement, a movable contact coupled to the movable part, a member that biases the movable contact, a latch capable of switching between a first state in which movement of the movable contact is restricted and a second state in which movement is permitted, a part that accommodates the movable part and the movable contact therein, a fixed contact provided outside of the accommodating part, and a moving part that moves with the movable contact. The latch is switched to the second state when the movable contact has moved against the biasing force. The accommodating part contains a first region and a second region, which is on a side of the fixed contact with respect to the first region within a range of movement of the moving part. The first region has an inner diameter smaller than that of the second region.

摘要： A switchgear includes a movable part capable of reciprocating movement in first and second directions, a movable contact coupled to the movable part and capable of reciprocating movement relative to the movable part, a biasing member that biases the movable contact, a latch part capable of switching between a first state in which movement of the movable contact in the first direction is restricted and a second state in which movement of the movable contact in the first direction is permitted, and a fixed contact provided on a side of the first direction with respect to the movable contact. When the movable part and the movable contact move in the first direction, after movement for a predetermined distance, the movement of the movable contact is restricted by the latch part in the first state, and then, when the movable part has moved further in the first direction, the latch part is switched to the second state.
