Detailed Selection Guide

When buying wholesale automatic mains light switch kits, consider the following selection factors, especially for South African installations and procurement:

• Switching Load: Calculate your maximum load. For example, 10A at 230V AC supports up to 2.3kW (suitable for typical households or classroom circuits).
• Sensor Type: PIR is ideal for occupancy-based control; LDR/photocell for dusk/dawn; programmable for predictable schedules.
• Assembly/Ease of Installation: Pre-assembled kits simplify bulk deployments, while DIY kits offer cost savings and education benefits.
• Safety Considerations: Always use suitable enclosures. Ask about relay isolation and test with lower loads before large rollouts.
• Lead Times & Fulfilment: Check current stock with Communica; special bulk orders may require 2-7 working days for processing within South Africa.
