Title:
THROTTLE VALVE SWITCH DEVICE
Document Type and Number:
Japanese Patent JP3318150
Kind Code:
B2
Abstract:
PURPOSE: To reduce a cost and to reduce the size of the whole of a device by reducing a signal wire which outputs a detecting signal.
CONSTITUTION: By bringing a slide contact 13B, rotated according to the opening of a throttle valve, into slide contact with one of a fixed contact point 32 for a switch and fixed contact points 34A-34C for respective signals, a voltage from an input terminal 17 for a power source is divided by one of a resistor 33 for a division voltage and resistors 35A-35C for respective signals and three kinds of detecting signals having different voltages from each other are outputted to a single output terminal 36. This constitution discriminates, based on a voltage of a detecting signal, with which of the fixed contacts 34A-34C the slide contact 13B makes contact, namely, in which of an idle position, a correction position, and a full position a throttle valve is situated and minimizes the number of output terminals to output a detecting signal.
