Y1011U2C202NQ – C&K

The Y1011U2C202NQ keylock switch, manufactured by C&K, is a two-position, single-pole double-throw (SPDT) electromechanical switch designed for keyed access control applications. It features a maintained contact configuration, providing a stable electrical connection in each of its two key-actuated positions. The switch is rated for a maximum current of 4A at 125VAC, making it suitable for controlling moderate power loads. The key mechanism provides a physical security element, preventing unauthorized circuit activation or deactivation. The switch body likely incorporates robust materials to withstand repeated actuation and environmental factors. The “202” suffix likely refers to a specific key code or tumbler configuration for security differentiation, preventing cross-operation with other keylock switches using different key codes. Further specifications, such as contact resistance, insulation resistance, and operating temperature range, would be available in the manufacturer’s datasheet.
