Embodiment Construction
[0014] figure 2 The described motorcycle power switch flameout circuit is an embodiment of a non-contact ignition switch, including: a whole vehicle power switch circuit, a single-pole single-throw switch controlled by a car key, an isolation circuit, and a flameout control circuit.
[0015] The whole vehicle power switch circuit is composed of a P-channel field effect transistor Q1, a 15V Zener diode D1, and resistors R1 and R2, the source of the power switch tube is connected to the positive pole 2 of the battery, and the drain is connected to the whole vehicle power supply 1. The system ground terminal 5 is connected to The negative electrode of the battery, Zener diode D1 and resistor R2 are connected in parallel between the source and gate of field effect transistor Q1. Zener diode D1 is to protect the source-gate voltage of the field effect transistor from exceeding 15V, and resistor R1 is the voltage regulator of diode D1. The current limiting resistor prevents the vol...
