The component 50 includes a housing 52 having an attachment portion 52M to which the communication unit 92 including the position information detection portion 92A is detachably attached, a control portion 54 provided in the housing 52, and an electrical connector 56A detachable from the communication unit 92. and an electric connection portion 56 electrically connected to the control portion 54, and an electric component 58 controlled by the control portion 54, and the position information detection portion 92A receives radio waves from the outside. and the control unit 54 is configured to communicate with the communication unit 92 via the electrical connection unit 56 when the electrical connector 56A is connected to the communication unit 92. other configurations may be omitted.

The component 50 includes a housing 52 having an attachment portion 52M to which the communication unit 92 is detachably attached, a control portion 54 provided in the housing 52, and an electrical connection portion 56 having an electrical connector 56A detachable from the communication unit 92. , a first storage portion 54A for storing first identification information, and an electric component 58 controlled by the control portion 54, the communication unit 92 receiving control signals from the external device 42 and sending signals to the external device 42. a wireless communication unit 92D configured to perform at least one of: transmission of a control signal of; and a second storage unit 92C that stores second identification information. 92D, and the control section 54 is configured to communicate with the communication unit 92 via the electrical connection section 56 in a state in which the electrical connector 56A is connected to the communication unit 92, and the second identification information is If the control unit 54 is configured to limit the function of the electrical component 58 when it does not correspond to the first identification information, other components may be omitted.

As used herein, the phrase "at least one" means "one or more" of the desired option. As an example, the phrase "at least one" as used herein means "only one option" or "both of the two options" if the number of options is two. As another example, the expression "at least one" used herein means "only one option" or "any combination of two or more options" if the number of options is three or more. means.
