AS-10 12V Photoswitch Light Sensor Switch

This is a genuinely standalone automation device - no microcontroller, no code, no wiring to anything beyond the load itself and a 12V supply. An onboard photocell detects ambient light and directly drives a relay-style switch: dark triggers the load on, daylight switches it back off, all handled entirely within the device itself.

Rated for 10A at 12V and compatible with resistive, inductive, and capacitive load types, it comfortably handles LED, incandescent, and fluorescent lighting as well as small motor loads like exhaust fans. That broad load-type compatibility matters because inductive loads (fans, some ballasts) can trip a switch rated only for simple resistive loads if it isn't genuinely designed for the mixed load types this one supports.

Common uses are automatic garden, driveway, or security lighting that needs no separate controller, greenhouse or outdoor equipment that should run only at night (or only during daylight, wired in reverse), and any 12V load wanting simple photocell-triggered automation without a full smart-home or microcontroller setup.
