The DS213 is a compact black round pushbutton switch designed for small panel installations. It offers a momentary, selfreset action with no locking mechanism, making it ideal for simple pushtoactivate inputs in diverse electronics projects and control panels. The component is specified as 1 piece and features a 10 mm size with a small key hole mounting option, suitable for panels that require a slim, unobtrusive switch. Key benefits Momentary selfreset action: presses are momentary, returning to the off state after release to prevent unintended latch behavior in circuits. No lock design: straightforward operation without a locking mechanism, reducing user confusion and mechanical complexity. Compact 10 mm size: round button fits small panel cutouts while providing adequate tactile feedback for reliable actuation. Aesthetic and versatile: black finish and round form suit a wide range of enclosures and control panels. Mounting flexibility: designed for a small key hole mounting option and 10 mm installation, enabling secure integration in tight layouts. Key attributes Model: DS213 Color: Black Form factor: Round pushbutton switch Action: Selfresetting, momentary Locking: No lock Size: 10 mm diameter Mounting: Suitable for 10 mm panel openings; features a small key hole mounting characteristic Quantity: 1 piece Material: Not specified by the product listing Performance and compatibility notes Intended for continuous, repeated actuation in compact control interfaces. Suitable for applications where a nonlatching input is required from a small, unobtrusive switch. Specific electrical ratings, operating voltage/current, and mechanical durability are not provided in the listing; verify compatibility with your circuit and panel specifications before integration. Applications Small control panels in consumer electronics or DIY projects requiring a momentary push input. Arcade, vending, or instrumentation panels that need a compact, nonlatching pushbutton switch. Replacement switch in devices that previously used a DS213style momentary button, or in custom enclosures where a 10 mm diameter, selfreset button is appropriate.
