Abstract

A disconnecting switch includes a contact part that includes a stationary contact and a movable contact, a shaft that moves the movable contact relative to the stationary contact, an open/close mechanism part that moves the shaft back and forth freely between a closed contact position at which the movable contact contacts with the stationary contact and an open contact position at which the movable contact is separated from the stationary contact, and a housing that houses at least the contact part and the shaft. The open/close mechanism part includes an operation lever, an arm that rotates according to an operation of the operation lever to move the shaft between the open contact position and the closed contact position, and a wheel rotatably attached to the housing. The arm has a rotation slot in which the wheel is placed so that the wheel moves when the arm rotates.

Claims9

Dependent claims

A disconnecting switch comprising:

a contact part that includes a stationary contact and a movable contact configured to be brought into contact with and separate from the stationary contact freely;
a shaft configured to move the movable contact back and forth freely relative to the stationary contact;
an open/close mechanism part configured to move the shaft back and forth freely between a closed contact position at which the movable contact is in contact with the stationary contact and an open contact position at which the movable contact is out of contact from the stationary contact;
and
a housing in which at least the contact part and the shaft is housed, wherein
the open/close mechanism part includes an operation lever which is disposed so that an operation portion thereof protrudes outward from the housing, an arm configured to rotate according to an operation of the operation lever to move the shaft between the open contact position and the closed contact position, and a wheel which is rotatably attached to the housing, and
the arm is provided with a rotation slot in which the wheel is placed so that the wheel moves when the arm rotates.
