{"title":"Adafruit STEMMA Non-Latching Mini Relay","handle":"adafruit-stemma-non-latching-mini-relay","url":"/products/adafruit-stemma-non-latching-mini-relay","description":"The Adafruit STEMMA Non-Latching Mini Relay lets you switch lamps, fans, solenoids, and other small appliances (up to 250 VAC/DC) using any 3V or 5V microcontroller — no soldering, flyback diodes, or level shifting required. Just connect via the JST-PH STEMMA connector and toggle the signal pin high to activate the relay.\n\nThe relay features push-in spring terminals for the switched load (24–18 AWG wire) and a red LED indicator when active. It draws approximately 50 mA when the coil is energised and returns to the open (NC) state if power is lost.\n\nKey Features\n\n\nNon-Latching Relay – COM connects to NO when signal is high; returns to NC when power is removed\n\nSTEMMA JST-PH Connector – Plug-and-play with 3V or 5V microcontrollers\n\nPush-In Spring Terminals – Tool-free wire connection for 24–18 AWG\n\nRed LED Indicator – Lights when relay is active\n\nBuilt-In Protection – Flyback diode, level shifting, and pin protection onboard\n\nOptional Second Switch – Solder pads for a 3-pin terminal block on the side\n\n\nSwitching Capacity\n\nUp to 2A at 30 VDC or ~40 VAC (resistive load)\nUp to 0.5A at 120 VAC\nUp to 0.6A at 250 VAC\nUp to 0.3A at 110 VDC\nRecommended maximum: 60W for general use\n\n\nIdeal For\n\nSwitching lamps, fans, and small appliances\nSolenoid and valve control\nHome automation projects\nCircuit Playground and micro:bit projects (with alligator clip cable)\n\n\nPackage Contents\n\n1× STEMMA Non-Latching Mini Relay board (assembled and tested)\n\n\n\nWarning: If using with voltages above 24V, exercise caution. High-voltage wiring requires experience and proper safety practices. De-rate for reactive/inductive loads. Cable not included.\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":4736,"title":"Default Title","sku":"AF-4409","price":11.6,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
