摘要： Electrovalves are opened in automobile piping of a brake line, a clutch line and a fuel line by a current through normally open contacts of a plurality of control relays and through normally closed contacts of an interlocking relay. The control relays are operated by selected switches of a plurality of push-button switches while the interlocking relay is operated by the non-selected switches of the plurality of switches. The control relays are interconnected so that the selected push-button switches must be operated in a selected sequence. All the relays have holding circuits.
