The Y201132C201NQ is a dual-pole (DP) 4-tumbler switchlock with 45° indexing and key-pull positions at locations 1 and 3, designed for secure access control applications. It features anti-static switch capability exceeding 20 kV DC static resistance at sea level, with a contact rating of 4 amps at 125 V AC or 28 V DC, and 2 amps at 250 V AC (UL/CSA certified). The switchlock incorporates a 4-tumbler lock with detent and anti-static switch (lock type B), nickel-plated brass keys with code on lock face, and solder lug with notch termination (01). Key technical characteristics include contact resistance below 10 mO typical at 2–4 V DC with 100 mA, insulation resistance of 10? O minimum, dielectric strength of 1,000 Vrms minimum at sea level, and an electrical life of 10,000 make-and-break cycles at full load. This switchlock is ideal for point-of-sale terminals, cash registers, and computer security applications where reliable keyed access and anti-static protection are essential.
