For Craftsman CompressorSunday, April 01, 2012
Switch was almost a perfect fit. The unloader line had to be re-bent to fit but other than that it fit in the same foot print and works perfect. Has on/off switch that I needed and other models did not have it. Dual contact was also needed for 220v operation. Price and shipping was best I found. Happy with the entire transaction.
Was a direct replacement for original unit
Nothing as far as my requirements went, it had everything I needed

Don't know anything about this item, only that Square D has a good reputation.
