Abstract
A seat belt buckle engagement detector of the invention includes a by-pass or direct circuit for supplying electricity from a battery to one end of a seat belt warning lamp through a current limiting resistance. With this by-pass circuit, even if an ignition switch is turned off, in case a buckle switch is turned on, a signal of a ground potential is inputted to a seat belt system. In case the buckle switch is turned off, a signal of a potential corresponding to a voltage of the battery is inputted to the seat belt system. Thus, the seat belt system can carry out a desired process even under a condition where the ignition switch is turned off.
