Abstract
A controller to permit a sewing machine operator to control a sewing machine drive motor from control members located in close proximity to the needle bar. Means are provided to permit the operator to select the sewing speed and the needle stop position prior to commencing the sewing process. The operator may thereafter control the sewing process by light finger pressure applied to the control members without attention being distracted from the work feeding area. The operator may suspend the sewing process by removing pressure from the control members. The sewing machine will thereafter stop with the needle bar in the selected position. A reset circuit is provided to prevent the operator from unintentionally actuating the sewing machine drive motor.
