Abstract
The invention provides a clutch component of a switch device. The clutch component comprises a clutch gear (10) and an operation part (20), wherein the clutch gear can be driven by a motor component (70) of the switch device and transmits to a switching gear (80) of the switch device so as to complete switching of connection states of the switch device. The operation part comprises an operation portion (22) and a contact portion (24), wherein the operation portion can drive the contact portion to move, so that the contact portion pushes the clutch gear along the clutch direction, and the clutch gear separates from transmission with the motor component. By the aid of the above structure, when the switch device is set in a manual mode, an operation handle drives the switching gear which transmits to the motor component without using the clutch gear, and thereby, operation torque of the operation handle is reduced, and even if the motor component still works, damage or safety accidents caused by mutual interference between the motor component and the switching gear can be avoided.
