Device for the transmission to an instrument panel of information on the state of a plurality of electrical contacts

摘要

Device for the transmission to an instrument panel of information on the state of a plurality of electrical contacts. It comprises a conductor 5 connected to the contacts 1-4 via resistors of predetermined values, and a reference voltage is applied to the conductor 5. The current carried by the conductor is measured 8 and displayed 6. The values of the resistors of the contacts 1-4 are such that the currents carried in all configurations of opening and closing of the contacts are all different. The device applies well to vehicle instrument panels. <IMAGE>
