The black housing and twopin configuration provide a simple, maintenance switch for panel or enclosure installations. Each switch is rated at 1 A up to 250 V AC, and the pack includes both PBS11A and PBS11B variants. Key features and benefits Latching, selflocking action: push once to turn on, push again to turn off. The switch maintains its state without continuous pressure, reducing wear from heldin positions. Compact 12 mm size: suitable for spaceconstrained applications and panel openings with a small footprint. Simple 2pin connection: straightforward wiring for quick integration into projects and systems. Electrical rating: 1 A at 250 V AC, providing adequate performance for lowtomoderate current control tasks. Black housing: unobtrusive appearance that fits a variety of enclosures and typologies. Product attributes Brand: ElectronicSwitch Models included: PBS11A and PBS11B Quantity: 10 pieces per pack Size: 12 mm push button Action: selflocking, latching Terminals: 2pin configuration Electrical rating: 1 A at 250 V AC Color: black Compatible applications and use cases DIY electronics and microcontroller projects: use as a reliable power switch to control LEDs, sensors, or small modules with a simple pushbutton interface. Enclosures and instrument panels: ideal for panelmounted control where a latched on/off state is preferred over momentary action. Small household or hobby devices: suitable as a control switch in projects such as portable gadgets, model routers, or compact home automation devices. What to consider Verify the panel hole size and mounting method to ensure proper fit with your enclosure. This switch is rated for AC applications up to 250 V and 1 A; if your use involves DC circuits or higher current, select a component rated for those conditions. This pack provides a balanced mix of PBS11A and PBS11B latching push button switches in a compact 12 mm form factor, suitable for a wide range of control tasks in electronics projects and panel installations.
