Title:
POSITION DETECTING SWITCH
Document Type and Number:
Japanese Patent JP3724669
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To lower a cost needed for a circuit part or wiring to realize cost reduction as a whole.
SOLUTION: A switch circuit 1 is constituted of partial pressure element R1-R6 for pressure-dividing reference voltage inputted from outside via a reference voltage inputting terminal 10, a fixed contact 30 for forming metallic patterns 31-33 on a base board, and a movable contact 20 for slidably contacting on the metallic patterns 31-33. In the switch circuit 1, voltage is divided by a partial pressure ratio in accordance with the presently selected position of an object whose position is to be detected, and also the partial voltage is outputted as an analog signal. The partial pressure element R2-R6, for switching the partial pressure ratio out of partial pressure elements R1-R6, are connected in parallel with each other via the fixed contact 30 and the movable contact 20.
