carried by the needle bar referring to fig1 and 3 a switch 110 is carried by control panel 76 and has its contacts in parallel through lines 112 and 114 with the output line 60 of the digital to analog converter 52 iadd preferably the circuit is arranged such that when the switch 110 is open the bight will be reduced for multiple needle sewing and when the switch 110 is closed a wider bight will be available for single needle sewing iaddend it will be recalled as discussed above the digital to analog converter 52 puts out an analog signal which is converted from the digital information from the memory to provide a control signal for the bight in accordance with a selected pattern in order to reduce the signal from the digital to analog converter 52 a fixed resistance in the form of a resistor 116 is placed in line 114 which resistor 116 has a resistance selected so that it will reduce the analog voltage from the digital to analog converter in an amount proportion to the number of needles which in the case of switch 110 and its associated circuit in the preferred embodiment illustrated is selected for twin or two needle sewing thus for example the resistance of resistor 116 may be such to reduce iadd influence iaddend the output from the digital to analog converter by.
