The purpose of a switch is to enable the local user and the administrator operate the lighting more easily.
Each type of switch, including classic mechanical switches, digital switches, to touch panels; all have their own indispensable values. Each must be utilized to their fullest to fulfill their value.

1. Classic switches
   1. Great variety: When the interior design needs to be fancy and sophisticated, plain looking switches will not do, so this rule out most digital switches, and only high-end classic switches will do.
   2. Manual operation is frequent, and it is sometimes unavoidable that the switch is roughly handled, mechanical switches are more durable. Classrooms, restrooms, hallways, meeting rooms, reception rooms and other public places all have wall switches and they must be reliable and durable to withstand the rigors of constant use.
   3. Maintenance considerations
      When it comes to materials and labor costs, mechanical switches are more practical, as replacement parts are more easily available and the maintenance technician are already trained on how to replace them.
   4. No training needed
2. Digital Switches
   1. Simplified wiring
      All of the digital switches can be linked together through a digital bus.
   2. Multiple switches control the same lighting circuit. (Especially useful for large areas)
   3. One switch can control multiple lighting circuits. (Especially useful for simplifying operation)
   4. Equipped with status feedback indicator for remote operation. (Enables operator to know the status of the local lights even when the line of sight is blocked)
   5. Even when there are lots of circuits, each would be labeled clearly and there is no confusion.
   6. The switches can be packed tightly together to occupy little space.
   7. Each individual switch can dynamically be reconfigured for different operation; they are not constrained by the physical layout of the circuit wiring.
3. Touch Panel
   1. The touch panel is a very user friendly type of digital switch. Among the unique features are: the button names can be user defined, type management is easier, and they are well suited for large number of lighting circuits.
   2. User adjustable schedule control
      An automated schedule is not fixed throughout the year, and needs to be adjusted for seasonal changes and for special holidays and occasions. The interface and operation should be simple enough that this can be independently made by the operator on the fly, otherwise it wouldn’t be used because it is too complicated.
   3. Remote operation over the network
      When it is necessary to control the lighting afar. Even the schedule can be changed thusly.
   4. During expansion, there is no need for additional switches nor the wiring needed for those switches, as additional buttons can simply be assigned from the same touch panel.
