I just read a thread regarding where to get basic electrical items. It was cable & toggle switches. The source was Radio Shack. After shaking my head since that would be one of the last places I would go due to price and poor selection, I decided to provide a list of sites where one can get almost anything they need without paying through the nose. Working retail for a number of years many years ago, including RS, I can tell you that is not where to go. Neither is Home Depot (I shop there all the time, but not for any of this), Lowes or any other hardware like store. Yes, they are usually convenient, but you will pay for it. Have said that, I also have worked for an electronics manufacture and have dealt with many mail order companies purchasing components, wire, cable & special components over the years. What I look for, depending on my needs are companies that buy up overstock and discontinued items are a fraction of the original cost. This is usually a large savings, but the selection varies and is not intensive. The first group of links fits into this category; http://www.mpja.com/ http://www.allelectronics.com/ https://www.bgmicro.com/login.aspx The next category is bulk wire. Copper is not cheap, cabling costs have risen considerable in the past 10 years. What I look for is stranded speaker wire with thinner, clear insulation for most wiring jobs unless I need single conductor and a specific color. I also like using 20 gauge, but it is harder to find. 18 & 22 are very coming, 20 is not. It';s a compromise between the two when you need more than 22 which is small and 18 which might be somewhat bulky depending on the application; http://www.cablewholesale.com/shop/bulk-cable.htm http://www.waytekwire.com/wps/portal/en/products Next are individual electronic components. Transistors, capacitors, diodes, IC's, etc. The two main players are Mouser & Digikey. Both are huge supply houses for just about anything electronic; http://www.mouser.com/search/default.aspx http://www.digikey.com/product-search/en http://www.onlinecomponents.com/productsearch.aspx Lastly, here are other sources that carry a assortment of items; http://www.web-tronics.com/electronic-parts-and-general-supplies http://nteinc.com/ Please note, many of these sites also carry other items that cross over into the other categories. I tried to group them together as best as possible. Also note, while some might be great at one line of products, they might be the opposite at another. If anyone can add to the list, please do so.
