Abstract: The switch input processing module has: a control unit; a first external connection terminal to which either an analog signal of an analog signal system or a serial signal of a serial signal system is supplied; an analog signal transmission and serial signal transmission line which is disposed between the first external connection terminal and the control unit; and a second external connection terminal to which a determination signal indicating that either the analog signal system or the serial signal system is connected to the first external connection terminal is supplied. When the control unit determines that the determination signal indicates connection of the serial signal system, the control unit makes the serial signal transmission line conductive. When the control unit determines that the determination signal indicates connection of the analog signal system, the control unit makes the serial signal transmission line nonconductive.

Abstract: A multiple communication system used in an automobile includes miniaturized multi-function electric units. Each electric unit is composed of a CPU and a bus driver, and the CPU is connected to a bus line through the bus driver. The CPU of each of the electric units includes a communication processing program, and communication can be carried out among the electric units through the bus line using the communication processing program.

Further, since the bus drivers of small size are used, the electric units can be miniaturized. Further, the communication processing program of each CPU can be rewritten through the bus line.

A lever is pivotably positioned over the rigid member and includes a first projection contacting the rigid member near the first elastic click member, and a second projection contacting the rigid member near the second elastic click member. When the lever is pivoted a first angular amount in a clockwise direction, the first projection presses against the rigid member, causing the rigid member to rotate with respect to the second elastic member to buckle the first elastic click member. Further pivoting of the lever in the clockwise direction causes the rigid member to rotate with respect to the buckled first elastic click member, thereby buckling the second elastic click member.
