I posted a simular reply not too long ago. I have been using for years "AutomationDirect.com". They are an on-line company in Atlanta and you can pick up roller, snap action switches FAR LESS than anywhere else! I am an engineer who designs and builds automation for a living and I am always searching for a good deal, and a good deal more! Give then a look, I assure you will not be dissatisified! The sell sensors, switches, fiber-optics, enclosures all at a very good price. Hope this helps, let me know what you think.
