For sale is a Set of 2 REES Mushroom Push Button Safety Switches 600VAC 347S 250VDC Heavy Duty Made in USA This part comes from a 100 ton OBI Punch Press that broke its crankshaft, so the rest of the parts are presumably working. I am not able to test them, so there is no guarantee they are working. However, if you receive this part and it is not working, you are welcome to return it for a full refund. You would just be responsible for ALL shipping, both ways. Thanks.
