Macrostart switches replace voltage or current relays and centrifugal switches for most motors. Patent Numbers: 4761601, 4468604 and 4,468,604
Product selection: Find voltage and amperage (or horsepower) and pick desired time for switch to energize the start windings. 1/3 second is usually for pumps, compressors, etc. 1/2 second is usually for fans, disposals, etc. 1 second is usually for capacitor and split-phase motors.
