Welcome to TSI Security Acquisition Corp - Home of the original and most competitively priced ATO and ATC Fuse Plugs at $2.10 per unit wholesale to the public.
TSI Security Acquisition Corp. (“TSI”) is the original designer and manufacturer of the formerly U.S. patented ATO and ATC Fuse Plugs previously sold by Littelfuse (under the name Add-A-Circuit) and Cooper Bussman (known as HHA Add-A-Line) as well as Wirthco Engineering, Haines Enterprises and other distributors of automotive parts where the original Fuse Plugs have been referred to as Circuit Tap Adapters and Tapa Circuits.
The innovative dual slot design provides a slot for the existing OEM circuit and a second slot for a new circuit for a mobile electronic device eliminating the need for an additional fuse holder.
Purchase these products directly from TSI, the original manufacturer and eliminate the middleman mark up in price by our former distributors. The products sold by our former distributors are imported from China and may not be subject to rigorous quality standards required by IS0 9001 or RoHS.
