Abstract
A connecting structure for an indicator display is provided that utilizes only a single electric wire of a wire harness used in a circuit to display gear position. The circuit is designed so that the resistances of respective circuits corresponding to the gear positions in an inhibitor switch of the automatic transmission are made different. A judging circuit is provided to discriminate and judge electric current values in a gear indicator. A respective display lamp corresponding to the selected gear position is lighted, and the connection of the inhibitor switch with the gear indicator is carried out by a wire harness having a single electric wire.
Claims4
A connecting structure for an indicator display, in which a wire harness connects an inhibitor switch which outputs signals corresponding to respective gear positions provided on an automatic transmission with a gear indicator which indicates a gear position in accordance with the input of the above-mentioned signals provided in a vehicle information display in a passenger compartment, said connecting structure comprising:
- an output circuit of said inhibitor switch including a plurality of circuits having resistance values different from each other for each respective gear position, said output circuit forming a signal output by combining the output side of said plurality of circuits;
- a judgment circuit provided to said gear indicator that discriminates and judges different electric current values through one signal input;
- and
- a wire harness that connects said signal output of said inhibitor switch and said signal input of said gear indicator, thereby actuating the gear indicator.
A connecting structure for an indicator display of an automatic transmission, said connecting structure comprising:
- an inhibitor switch including a connecting piece and an output circuit, said output circuit comprising a plurality of circuits having resistance values different from each other, each resistance value assigned to a respective gear position of the automatic transmission, said output circuit forming a signal output by connecting an output of each of said plurality of circuits together, wherein said signal output transmits signals corresponding to respective gear positions provided on the automatic transmission;
- a gear indicator that receives the transmitted signals to indicate a gear position in a vehicle information display, said gear indicator including a judgment circuit that discriminates and judges different electric current values provided by the different resistance values through one signal input;
- and
- a wire harness that connects said signal output of said inhibitor switch and said signal input of said gear indicator, thereby permitting actuation of the gear indicator.
