This is one of the most popular uses for this switch. It allows you to toggle LED lighting systems on your RC model using a spare channel on your transmitter, making it ideal for scale lighting effects and functional headlights or taillights.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What battery types are compatible with the 4.8V–8.4V input range?\u003c\/h4\u003e\n\u003cp\u003eA: The 4.8V–8.4V input range is compatible with standard 4-cell NiMH\/NiCd packs (4.8V), 5-cell NiMH\/NiCd packs (6V), and 2S LiPo battery packs (7.4V nominal \/ 8.4V fully charged) — covering most common RC power setups.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is any soldering required to install this relay switch?\u003c\/h4\u003e\n\u003cp\u003eA: The signal side connects directly to your RC receiver via a standard servo connector — no soldering needed there. However, the switching terminals (where you connect the device being controlled, such as LED strips) may require soldering or use of screw terminals depending on your wiring setup.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What RC receivers is this PWM relay switch compatible with?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This relay switch is compatible with any standard RC receiver that outputs a 3–5V PWM pulse width signal in the 900–2100µs range.
