ABSTRACT:
A switch unit allows a user to perform an on-and-off switching control of a load which is installed in a certain place without having the user move to the load position and confirm the control status of the load. The switch unit includes a local switching unit having a plurality of buttons each coresponding to each load which is installed in a current place, for directly selecting a load to be switching-controlled, an overall switching unit fabricated in the form of a dial, for selecting a load to be switching-controlled, an overall display unit having a number of LEDs, for displaying the switching control state of each load, an all-off switch which is slightly sunk from the surface of the switch unit, for switching all the loads entirely, and a remote controller signal receiver for receiving a remote controller signal. The switch unit further includes a FND display unit for displaying a load corresponding to the current dial position in the overall switching unit with a numerical symbol. Thus, a power source can be easily, conveniently and efficiently used and managed, to thereby provide users with a considerable power saving effect and conveniences.
