Releasing the wire requires pressing the orange lever (or using a small screwdriver in the release slot) to open the spring clamp. These connectors are widely used in residential and commercial lighting installations, junction boxes, and appliance wiring where fast, reliable, and reusable connections are required.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModels:\u003c\/strong\u003e CH2 (2-pole) and CH3 (3-pole)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type:\u003c\/strong\u003e Spring-loaded push-in clamp (tool-free insertion)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Range:\u003c\/strong\u003e 0.5–2.5mm² (20–14AWG), solid or stranded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 24A (per pole)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 450V AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material:\u003c\/strong\u003e PA66 nylon, UL94 V-0 flame retardant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Material:\u003c\/strong\u003e Copper alloy, tin-plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e -30°C to +105°C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 100 pieces per pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePush-In Spring Connector vs Screw Terminal vs Wire Nut — Comparison\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePush-in spring (this product):\u003c\/strong\u003e Tool-free, fast (under 5 seconds per wire), reusable, consistent clamping force regardless of installer skill.

They use the same push-in spring mechanism and accept the same wire gauges. WAGO 221 is the original; CH2\/CH3 are compatible alternatives at lower cost.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"Can I use push-in connectors for stranded wire?\"\u003c\/em\u003e — Yes. These connectors accept both solid and stranded wire (0.5–2.5mm²). For stranded wire, ensure the stripped end is not frayed — twist the strands together before insertion to prevent individual strands from missing the contact area.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"How do I release a wire from a push-in connector?\"\u003c\/em\u003e — Press the orange lever (or insert a small flat screwdriver into the release slot) to open the spring clamp, then pull the wire straight out. Do not pull the wire without releasing the clamp — this damages the conductor and may leave strands inside the connector.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"Are these connectors suitable for outdoor or damp locations?\"\u003c\/em\u003e — Standard CH2\/CH3 connectors are rated for dry indoor use. For outdoor or damp locations, use IP-rated junction boxes and ensure the connectors are not directly exposed to moisture. The connector housing is not waterproof.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"What is the maximum wire size for CH3 connectors?\"\u003c\/em\u003e — 2.5mm² (14AWG) maximum. For larger wire gauges (4mm² and above), use screw terminal blocks or larger spring terminal connectors rated for the wire size.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLighting:\u003c\/strong\u003e LED driver connections, ceiling light junction boxes, downlight wiring, strip light power connections\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHome wiring:\u003c\/strong\u003e Junction box splices, switch loop connections, outlet daisy-chaining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAppliances:\u003c\/strong\u003e Internal appliance wiring, heating element connections, motor control wiring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCommercial:\u003c\/strong\u003e Office lighting circuits, retail display wiring, signage power connections\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDIY electronics:\u003c\/strong\u003e Prototype wiring, breadboard-to-terminal connections, sensor power distribution\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cp\u003e100 pieces — CH2 (2-pole) or CH3 (3-pole) spring-loaded push-wire connectors as selected above.\u003c\/p\u003e","brand":"Cable Parts Online","offers":[{"title":"CH-2 \/ 100PCS","offer_id":47850770104565,"sku":"14:200004889#CH-2;200001249:202408830#100PCS","price":38.05,"currency_code":"USD","in_stock":true},{"title":"CH-3 \/ 100PCS","offer_id":47850770137333,"sku":"14:200004890#CH-3;200001249:202408830#100PCS","price":48.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0732\/3494\/0149\/files\/S3d5f1d037e074cd7b57ddebb2896e187b.webp?v=1773899657","url":"https:\/\/www.csldmcml.com\/products\/ch2-ch3-quick-push-wire-connector-spring-terminal-block-2pin-3pin","provider":"Cable Parts Online","version":"1.0","type":"link"}
