1pc DS213 Green Round Button Switch — No Lock, SelfReset, 10MM Key Hole Compact, reliable momentary push button for panels and DIY projects. The DS213 is a green round button switch with a selfreset (momentary) action and no locking mechanism. Its small 10MM key hole (mounting hole) makes it easy to integrate into tight panels and enclosures. Sold as a single piece (1pc). Why choose this switch Simple, predictable operation: selfreset (momentary) action returns to the off position automatically — ideal where momentary control is required. Saves space: 10MM mounting hole fits compact panels and instrument clusters. Easy visual identification: green color provides an immediate, standard indication for start, go, or confirm functions. Straightforward installation: designed for panelmount use in small control or hobby applications. Key attributes Model: DS213 Color: Green Shape: Round button Action: No lock, selfreset (momentary) Mounting: Small key hole / panel hole — 10MM Quantity: 1pc Functionality and compatibility Momentary push action (selfreset) — press to activate, release to deactivate. Intended for panelmount applications that accept a 10MM round button hole. Suitable for lowvoltage control panels, instrument clusters, hobby electronics, and equipment where a nonlatching start or reset control is required. Typical use cases Control panels: Use as a start, stop, or confirm button on compact control panels where a momentary input is preferred. DIY electronics and prototyping: Convenient momentary input for microcontroller projects, test rigs, and small enclosures. Machinery and instruments: Pushtoreset or pushtotest functions in compact instruments and displays requiring a clearly marked green control. Notes for installers Verify the panel hole diameter and clearance before mounting — the DS213 is specified for a 10MM mounting/key hole. Designed as a nonlocking, momentary switch (selfreset) — not intended for latching on/off control. This DS213 green round button switch provides a compact, easytoinstall momentary control option where a 10MM panel mounting and nolock operation are required.
