- The operation status of each switch is detected by the control and is transmitted as an operation signal to the A/C amp. via LIN communication.
- The following switch specification control was adopted.
- Temperature control : Dial type
- Air outlet control : Push-return type
- Air inlet control : Push-return type
- Air flow control : Push-return type
- A/C compressor ON/OFF : Push-return type
| note | Regarding the push switches : Refer to the following for the differences between push-lock types and push-return types. |
| Operation | Push-lock type | Push-return type |
| Switch ON operation | | |
| Switch OFF operation | |
Push-lock type
- Switch ON operation: At the time of switch ON operation, the switch is pushed from the reference point
to the pushed position 
, and the switch turns ON. When the switch is released from this position, the switch returns from the pushed position to the hold position 
, and the switch position is held there. - Switch OFF operation: At the time of the switch OFF operation, the switch is pushed from the hold position to the pushed position . When the switch is released from this position, the switch returns from the pushed position to the reference point , and the switch turns OFF.
Push-return type
- Switch ON operation: At the time of the switch ON operation, the switch is pushed from the reference point to the pushed position , and the switch turns ON. When the switch is released from this position, the switch returns from the pushed position to the reference point .
- Switch OFF operation: At the time of the switch OFF operation, the switch is pushed from the reference point to the pushed position , and the switch turns OFF. When the switch is released from this position, the switch returns from the pushed position to the reference point .
