Abstract
In a vehicle-mounted electrical component, potentially redundant resistances 4d, 4h, 4i and the corresponding voltage detecting circuit 5d, or the terminals 21, 22, 23, 24 and the switch for turning the switch interposed between the terminals 21 and 22, and the terminals 23 and 24 ON and OFF are exposed on the external surface of the main body so that setting according to the specifications can be performed outside the main body.
Claims4
A vehicle-mounted electrical component to be connected between a prescribed power source and a plurality of loads, said comprising:
- a main body of the vehicle-mounted electrical component;
- a plurality of resistances positioned within said body and connected between said each individual load and said power source;
- a voltage detector positioned in said body for detecting a break in said individual load by detecting voltage drop at each resistance individually;
- a potentially redundant resistance connecting terminal to be connected at least to said detector resistance and said voltage detector that can be redundant depending on the number of said loads mounted thereto out of said detector resistances and said voltage detector;
- and
- an intermediate connecting terminal connected to the power source connecting terminal to be connected to said power source, and each assigned to said each individual potentially redundant resistance connecting terminal;
- wherein said potentially redundant resistance connecting terminal and said intermediate connecting terminal are formed in parallel with respect to each other exposed on the external surface of the main body of said vehicle-mounted electrical component so that they can be short-circuited with respect to each other by the prescribed external connecting member.
