とするエンジン回転数検出器。 Consists of a cigarette plug 4, a pulsating current detection circuit 5, a memory circuit 15, a comparator 16, and a relay circuit 8 for controlling the load.The pulsating current is detected through the cigarette plug 4 by detecting the voltage including the pulsating current generated from the vehicle's generator. A comparator 16 compares data corresponding to the frequency of the pulsating flow supplied to the circuit 5 and obtained by the pulsating flow detection circuit 5 with data stored in advance in the memory circuit 15, and operates the relay circuit 8 based on the comparison result. An engine rotation speed detector characterized by:
