The Y101132C803NB is a 4-tumbler switchlock featuring single-pole (SP) operation with 45° indexing and key-pull capability at position 1. This switchlock incorporates an anti-static design that exceeds 20 kV DC static resistance at sea level between the lock body and terminals, making it suitable for sensitive electronic environments. The device is rated for 4 amps at 125 V AC or 28 V DC, with a contact resistance below 10 mO typical and an electrical life of 10,000 make-and-break cycles at full load. The switchlock features nickel-plated brass keys with code stamping and is available with solder lug terminations. Common applications include point-of-sale terminals, cash registers, and computer access control systems where secure keyed switching and static protection are required.
