<p>PURPOSE:To secure a hazard function even when a failure is generated in a hazard switch. CONSTITUTION:In this multiplex transmitter, a first node inputting a signal from a first switch, a second node inputting a signal from a second switch and a third node controlling an auxiliary machine to execute a first operation in response to a prescribed operation by the first switch are connected to a common transmission line. The feature of the transmitter is that the second node is provided with a means for detecting the operation of a first pattern of the second switch by an operator and a means transmitting to the third node an instruction so that the auxiliary machine executes a first operation.</p> |
