Abstract

The movable body includes a pivot and a contact portion. The pivot is rotatably supported. The contact portion is disposed at a position contactable with a contact piece. The movable body rotates around the pivot and presses the contact piece via the contact portion to move the second contact close to the first contact. The actuator presses the movable body to rotate the movable body around the pivot. The contact piece has a curved portion located between the second contact and the support. The pivot is located on a side where the support is disposed with respect to the curved portion. The actuator includes a pressing member which presses the movable body. The pressing member moves in an axial direction of the pressing member to press the movable body.

Dependent claims

A relay comprising:

a first contact;
a second contact disposed at a position facing the first contact;
a contact piece to which the second contact is attached;
a support configured to support the contact piece;
a movable body that includes a pivot rotatably supported and a contact portion disposed at a position contactable with the contact piece, the movable body configured to rotate around the pivot and press the contact piece via the contact portion to move the second contact close to the first contact;
and
an actuator configured to press the movable body to rotate the movable body around the pivot, wherein
the contact piece includes a curved portion located between the second contact and the support,
the pivot is located on a side where the support is disposed with respect to the curved portion,
the actuator includes a pressing member configured to press the movable body, and
the pressing member moves in a direction of an axis of the pressing member to press the movable body.
