INSULATION-DRIVING ARM OF SWITCH

摘要

The switch insulating driving arm (1) is used for improving an impact resistance. The driving arm for transmitting a driving force of switch actuator to a contact device (5) is inserted into a main body of the driving arm, being divided from a combining device (3). The material of the combining device is more flexible and has a higher melting point than that of the arm's main body, and the linear expansion coefficient of the combining device's material being more than that of the arm's main body.
