1pc DS211 White Round Button Switch with Lock — Selflocking, Small 10MM Key Hole A compact, lockable round push button designed to secure and maintain switch position when needed. The DS211 combines a simple white round actuator with a selflocking mechanism and a small 10MM key hole, making it ideal for applications that require deliberate, tamperresistant on/off control in a minimal footprint. Key benefits Prevents accidental operation: the lock feature keeps the switch in the chosen position until deliberately released. Maintains state without continuous pressure: selflocking action holds the switch mechanically for reliable on/off control. Compact and discreet: small 10MM key hole and round profile save panel space and suit tight installations. Easy to integrate: simple round design and neutral white finish blend into control panels and enclosures.
