This timer switch can automatically turn on/off various electric equipment according to the user-set time. With high precision and strong anti-interference capability, it is suitable for controlling street lamps, neon lamps, production equipment, radio and television systems, and other household or industrial appliances. Features: - Automatically controls electric devices based on preset times - 110V model has a built-in battery for data storage; 220V model requires 1 AA battery (not included) - Supports 10 ON and 10 OFF programs with timing range from 1 minute to 168 hours - Time settings can be repeated daily or weekly - Ideal for use with lighting systems, appliances, and industrial equipment Specifications: - Input Voltage: AC110V or AC220V (selectable) - Contact Voltage Rating: 180V to 240V - Switch Load Capacity: 10A (resistive), 10A (inductive) - Power Consumption: <1W - On/Off Operations: 10 ON and 10 OFF (manual or auto mode) - Timing Range: 1 minute to 168 hours - Operating Temperature: -20°C to 60°C - Humidity Range: <95% (non-condensing) - Time Accuracy: <0.5 seconds per day - Battery (for 220V model): 1 x AA (not included) - Dimensions: 120 x 74 x 51mm / 4.72 x 2.91 x 2 inches Instructions: 1. Set Clock (current time): Press and hold the "CLOCK" button, then use "WEEK", "HOUR", and "MINUTE" buttons to set the current time. 2. Set "1 ON": Press "TIMER", then use "HOUR" and "MINUTE" to set the first ON time. 3. Set "1 OFF": Press "TIMER" again to reach "1 OFF", then set the time using "HOUR" and "MINUTE". 4. Continue pressing "TIMER" to set up to 10 ON/OFF cycles. If fewer cycles are needed, set unused cycles to "--:--" by pressing "RESET/RECALL" to clear them. 5. After programming, press "CLOCK" to return to current time display. The system will also return automatically after 30 seconds of inactivity. 6. When connected, the red indicator light shows power supply status; the green light indicates switch closure. 7. Use "AUTO/MANU" button to manually open or close the circuit. Press until "off" appears, then press again to return to "Auto" mode. 8. Press "TIMER", then "WEEK" to select operating days (e.g., Mon/Wed/Fri, Mon-Fri, Sat/Sun, etc.).
