Abstract

The invention discloses a gradient dynamic resistor with a backward stepping switch. The gradient dynamic resistor is characterized by comprising an insulation container (G11), conductive liquid (G31), a solid (G21), a bottom electrode (G51), at least two gradient electrodes (U31, U32, U33 and U34), an electromagnetic coil (G41), a controlled-circuit first node (O+), a controlled-circuit second node (O-), a controlling-end first node (P+), a controlling-end second node (P-) and the at least two resistance-fixed resistor bodies (L1, L2, L3 and L4); the gradient dynamic resistor further comprises a bridge rectifier circuit (G60). The electronic circuit comprises the dynamic resistor. The independent power source of the electric tool comprises the dynamic resistor. According to the gradient dynamic resistor, the service life of contacts is long, manufacturing cost is low, and the gradient dynamic resistor is good in isolation and can be applied to high-power circuits such as weak power circuits, power circuits and ultrahigh-voltage power circuits.
