Actuator
First Claim
1. An address setting device for setting an address of a device in accordance with a control signal, the setting device comprising:
- an input terminal for receiving the control signal;
an output terminal for outputting the control signal; and
a setting circuit, connected to the input terminal and the output terminal, for setting an address value;
the setting circuit setting an initial value and disconnecting the input and output terminals from each other when reset; and
when the received control signal includes a predetermined value, the setting circuit changing the initial value to the predetermined value, which is used as the address value, and connecting the input and output terminals to each other.

Abstract
An actuator having satisfactory responsiveness. The actuator includes an input terminal, an output terminal, a switch connected between the output and input terminals, a driving portion, and a control circuit. When reset, the control circuit sets an initial value and opens the switch to disconnect the input and output terminals from each other. When the control circuit receives a control signal including a predetermined value, the control circuit changes the initial value to the predetermined value, which is used as the address value of the actuator and closes the switch to connect the input and output terminals to each other.
