This Iambic Key is my own design. I have worked through many revisions till I was happy with the result. Total dimensions are approx. 3 5/8 inch x 2 inch x 1 5/8 inch Total weight is approx. 1 7/8 oz. Connector: 1/8inch (3.5mm) stereo connector This key is perfect for portable operations or for someone who is looking to get into CW without investing in an expensive key. This Iambic Key comes with neodymium magnets that are adjustable for paddle tension. The magnets will simply be taped in and must be glued in by the end user. This allows you to make adjustments until you are happy. The movement of the paddles is also adjustable to your own preference. This allows you to set it up to your own preference. You can purchase the key at my etsy shop: www.thecheap3dprinter.etsy.com or on ebay: https://www.ebay.com/itm/122978938306?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1558.l2649 The key is available in a variety of colors and I will soon be adding the option to put your own call sign into the lid of the key. You can contact me directly at firstname.lastname@example.org The key will be warrantied for 30 days and I will replace any parts that may become damaged during that time.
