    Patent number: 6842123
    Abstract: A switch assembly (1) comprises a push-button section (52) and a push-button body (53) as an operation transmitting member, an LED box (54) and a contact-making contact (56) as a direct functioning member, and a communication-function incorporating contact (communications contact) (55) as an information input/output functioning member, as permitting these components to be connected with each other. Therefore, the switch assembly can respond to an operation given to the push-button body (52) by causing the contact-making contact (56) to provide an output for switching between a conductive state and a non-conductive state and by causing the communications contact (55) to output an information signal to a network.
