The conductive circuit 13 is disposed on the substrate 11, the conductive circuit 13 includes an input line 134, a ground line 133, and an output line 130, the output line 130 further includes a contact portion 130a, the conductive circuit 13 further includes at least one resistor 15, the resistor 15 is disposed on the substrate 11, and the resistor 15 is directly connected to the input line 134 and the ground line 133. The input line 134, the output line 130 and the ground line 133 may be made of copper. The copper material has better conductivity and better wear resistance. The material of the resistor 15 may be a carbon paste printed body made of carbon and gum. The carbon paste printing body has excellent printing performance, heat resistance, moisture resistance and stable electric conductivity. The product has the characteristics of stable resistance and small change rate, and the resistance of the product is more stable under the condition of being baked at higher temperature. Therefore, the stability of the control signal can be further improved.
