The 22 mm XB2ED21 and XB2ED33 self-locking (latching) knob switches are designed for panel mounting in standard 22 mm control openings. They provide reliable, stable actuation in industrial environments and are suitable for a range of control applications. Key specifications and features - Models: XB2ED21 and XB2ED33, 22 mm self-locking knob switches - Function: Self-locking / latching action that holds the selected state until deliberately changed - Electrical rating: 10 A current, 600 V voltage - Position options: 2-position and 3-position configurations available - XB2ED33 variant: Select button switch for choosing among defined states or functions - Form factor: 22 mm diameter footprint fits standard control panels - Use case suitability: Appropriate for control panels in manufacturing, packaging, and automation environments Precise information - Precise specifications can be provided based on specific checking instructions Use scenarios - Start/stop control in an industrial machine: Use a 2-position or 3-position setup to ensure the motor remains in its intended state until you actively change it, reducing the risk of unintended operation. - Mode or function selection on a control panel: Use the XB2ED33 select button switch to cycle through Auto, Manual, and other modes in a machine or process line, with a clear, latched indication of the current state. - Safety or maintenance operation on equipment: Use the latching action to hold a safe state (for example, during setup or fault isolation) and prevent accidental re-energizing without deliberate action.
