Abstract
A group of bus bars, forming a power circuit, are adhesively bonded to a surface of a control circuit board. Surface-mounting type relay switches are used as a switching unit for the power circuit. Contact-side terminals of each relay switch are mounted on the bus bar group while coil-side terminals thereof are mounted on the control circuit board. The opening and closing of relay contacts are controlled by a control circuit incorporated in the control circuit board.
Claims17
A circuit-constituting member comprising:
- a plurality of bus bars constituting a power circuit;
- a switching element disposed in the power circuit;
- and
- a control circuit board for controlling open/close of the switching element, wherein:
