ABSTRACT:
A switching device is provided which includes a moving body and a movement detection switch. The movement detection switch has a contact piece which is urged forwardly and which is moved by a spring so as to turn an electric contact on or off. When the moving body is shifted to a certain position, the electric contact is turned on or off through the contact piece. The moving body includes a floating head to be brought into contact with the contact piece, a guide for shifting the floating head in a moving direction of the contact piece, and a spring for urging the floating head in the moving direction of the contact piece. In a switching device of such a configuration, chattering can be prevented.
