Y2011U2V203NQ is a dual-pole (DP) 6-tumbler switchlock with 90° indexing and key-pull positions at 1 and 2, designed for secure access control in point-of-sale terminals, cash registers, and computer systems. The switch features a stainless steel facing (lock finish '2'), 6-tumbler tubular lock configuration with anti-static capability exceeding 20 kV DC static resistance, and solder lug termination with hole (03). Electrical specifications include a contact rating of 4 amps at 125 V AC or 28 V DC, contact resistance below 10 mO typical at 2–4 V DC with 100 mA, and an electrical life of 10,000 make-and-break cycles at full load. The switchlock provides reliable keyed switching with dielectric strength of 1,000 Vrms minimum and insulation resistance of 10? O minimum, making it suitable for applications requiring both security and durability.
