Drivers Seat Switch
The drivers seat switch is composed of three segments. The front switch parts conform to the seat structure, with cushion (bottom) and back segments. The Lumbar Switch, located aft of the seat segments, is round with an embossed square section.The front edge and back edge of the seat bottom are operated by different motors. These motors can be raised or lowered independently of each other. The seat bottom follows the movement of the cushion portion of the seat switch. When this portion of the switch is twisted, the seat motors will attempt to move the seat bottom to match the switch position. When the entire seat cushion switch is pulled to the "UP" or pushed to the "DOWN" position, both motors run together moving the front and back of the seat bottom at the same time, maintaining the angle setting of the seat cushion.
The forward/back motor is operated by the cushion portion of the seat switch. When it is pushed in the "FORWARD" position, the motor runs to drive the seat forward until the switch is released or the travel limit is reached. When the switch is pushed to the "BACK" position, the motor runs to drive the seat backward until the switch is released or the travel limit is reached. The polarity of the voltage to the motor is reversed during forward and backward movement. This reversed polarity causes the motor to run in the opposite direction.
The headrest is moved up or down by raising or lowering the back portion of the seat switch.
The recline function works by twisting the back portion of the seat switch. The seat back follows the switch movement to either recline towards the horizontal (down) or rise toward the vertical position (up).
The seat Lumbar Switch is a round button with an embossed square section. The Lumbar Support follows the switch movement. Pulling the switch "UP" will cause the Lumbar Support to rise and pressing the switch "DOWN" will cause the Lumbar Support to lower. Lumbar in and out movement is done by moving this switch "FORWARD" and "BACKWARD".
Each motor contains an electronic circuit breaker (PTC) which will trip at the end of travel. It resets only after voltage is removed from the motor.
