Specification Guide: Choosing Your Kit

When selecting and installing an automatic mains light switch kit, consider:

• Voltage & Load: Confirm switch or relay voltage rating (usually 220/230V AC - check LED/incandescent limits, max load in Amps or VA).
• Detection Range: For PIR or light kits: specify sensor angle, pickup distance, and delay times.
• Installation: Some kits fit standard wall boxes; others are DIN-rail or PCB-mountable for panels.
• Wiring: L, N, and load terminals clearly marked; some include screw terminals or flying leads.
• Assembly or Pre-built: Choose pre-soldered or true DIY solder kits (ideal for students and self-learning projects).
