Variable Speed Control: Provide variable speed to connected flex shaft rotary tool when stepping the pedal with varied pressure. This acts similar to the accelerator in a car, the more pressure the faster the speed. (Note: Please verify beforehand whether your device supports variable speed control) Momentary Foot Switch: After switching to high speed, some power tool can start or stop tools without manual switching. When maximum pressure is applied to the foot controller, the machine will maintain full speed operation Vacate Your Hands: The foot pedal performs switch operations, eliminating the need to vacate hands to turn on or off, which greatly saves time looking for switches and improves work efficiency. The power cord is extended to 70 in, and the cord for connecting to the motor is extended to 50 in Long-lasting and Reliable : The foot pedal adopts a sturdy shell and textured design for long service life and more efficient and reliable operation. The switch base is equipped with pads to help prevent slipping during work Wide Application: Momentary on/off foot switch for use with flex shaft motors (and other stationary power tools including bench lathes, scroll saws and drill presses). Allows you to sustain full speed in operation and permits user to turn tool on and off without using the manual switch CTISMICE rotary tools, flexible shaft machines and attachments are manufactured to industrial standards and are renowned for their quality and reliability. CTISMICE Foot Switch Features： 1. The momentary on/off foot switch is made of new ABS material, which has high strength and toughness and a longer service life than ordinary materials. 2. The power cord is extended to 70 in, and the cord for connecting to the motor is extended to 50 in Technical Specifications: Rated Voltage: 110-250V Frequency: 50Hz/60Hz Horsepower: 1/3HP Current Rating: 4 amp Additional Information: 1. Please confirm whether the machine to which the foot switch is connected supports variable speed control. If the machine does not support variable speed, the on/off foot pedal only functions as a momentary switch. 2. If the machine supports variable speed control, it can provide variable speed to the connected machine while pedaling at different pressures - Heavy duty for extended use. Some of the machines listed below are equipped with foot switches to help you achieve variable speed control. (Important Note: Whether variable speed control can be achieved depends on your machine model meeting the requirements.) Grinder, Carver, polisher, cutter, blender, sander, lathe, scroll saw, pottery wheel, rod wrapper, snow cone machine, corded drill, sewing machine, pottery wheel, bag sewing machine, electric bobbin winder,etc.
