CIRCUIT DEVICE CONTAINED IN JUNCTION BOX

摘要

PROBLEM TO BE SOLVED: To provide a circuit device capable of being commonly used and flexibly dealt with a circuit change in a junction box of a wire harness for an automobile. SOLUTION: A switch circuit device 14 can be detachably fixedly engaged with a recess 12 provided in an insulating plate body 12 for fixing a bus bar 11 for a shared circuit by changing its direction. The bar 11 disposes contacts A, B, C and D of a plurality of circuit patterns at a peripheral edge of the recess 12. Meanwhile, in the device 14, a bus bar 13 for switching a circuit is fixed onto an insulating board 14a fixedly engaged with the recess 12, and end contacts D, E of the bar 12 for switching the circuit are extended to the peripheral edge of the board 14a. When the device 14 is fixedly engaged with the recess 12 by changing its direction, the bar 13 for switching the circuit contacted with the bar 11 for the shared circuit is switched.
