{"title":"Adafruit Push-button Power Switch Breakout","handle":"adafruit-push-button-power-switch-breakout","url":"/products/adafruit-push-button-power-switch-breakout","description":"The Adafruit Push-button Power Switch Breakout lets you toggle DC power on and off with a simple button press. A latching analogue circuit uses a 3A P-FET to connect or disconnect the input to the output — press once to turn on, press again to turn off. It works with 3–14V DC at up to 3A, with only 0.5 µA quiescent current when off.\n\nA KILL pin allows your project to programmatically turn itself off — apply 1V or more to instantly disconnect the FET and keep power off even if the button is pressed. An on-board red LED indicates when the output is active.\n\nKey Features\n\n\nLatching Push-Button Control – Press once for on, press again for off; built-in debouncing\n\n3A P-FET Switch – Handles up to 3A continuous (FET may warm at max current)\n\n3–14V DC Range – Works with a wide range of DC power sources\n\n0.5 µA Quiescent Current – Ultra-low standby draw when off\n\nKILL Pin – Apply 1V+ to programmatically turn off the load and keep it off\n\nActive LED Indicator – Red LED lights up when output is on\n\nBreadboard Friendly – 0.1\" header and four mounting holes\n\nReplaceable Button – Includes a 12 mm tactile switch; solder in your own if preferred\n\n\nImportant Considerations\n\nDC voltages only (3–14V) — not for AC mains switching\nNo air-gap isolation (solid-state FET, not mechanical)\nBody diode in the FET allows reverse current if the load voltage exceeds the input\nVery bouncy switches may cause rapid on/off toggling instead of clean latching\n\n\nIdeal For\n\nBattery-powered project power control\nSelf-shutdown capability for microcontroller projects (via KILL pin)\nClean on/off switching for portable electronics\nReplacing toggle switches with a momentary push button\n\n\nPackage Contents\n\n1× Adafruit Push-button Power Switch Breakout (assembled and tested)\n1× 12 mm tactile button\n1× 0.1\" male header strip (requires soldering)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":7749,"title":"Default Title","sku":"AF-1400","price":12.03,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":11,"option1":"Default Title"}]}
