BN-LINK SU101D-2P In-Wall Digital Timer Switch, 18 Programs, Random Mode, 2-Pack

Seven-day scheduling lets you set lights or fans to turn on and off automatically, so everyday routines can run on a schedule you choose.

The BN-LINK SU101D-2P offers up to 18 on/off programs, with options for individual days or preset day combinations. A blue backlight makes the controls easier to see when setting the timer.

Use it for indoor switches that control porch, entryway, hallway, garage, or patio lighting, or a ceiling fan. The random mode can vary scheduled times while you’re away, and the daylight saving time function helps keep the schedule aligned when clocks change.

Everyday use

Set a schedule for the lights you want on at a particular time, then let the switch handle the routine. For example, a porch light can follow a recurring evening schedule without requiring a manual switch each day. Programs can use intervals as short as one minute, and you can select individual days or preset combinations to match weekday and weekend routines.

The random mode postpones on and off times by 0–30 minutes to create a lived-in appearance when you’re away. For ordinary daily operation, use AUTO mode, MANUAL mode lets you turn the connected light or fan on or off directly. The built-in rechargeable backup battery preserves settings during a power outage.

Strengths

Compared with a basic timer that follows a single repeating schedule, this switch provides multiple on/off programs and seven-day scheduling, giving you more control over when connected fixtures operate. Daylight saving time functionality is useful for schedules that need to stay in step with seasonal clock changes. The backlit display also makes programming more practical in dim rooms.

It supports single-pole and 3-way setups, including control of the same light from two locations. That makes it a useful format for spaces such as hallways, stairways, garages, and larger rooms where a fixture is switched from separate points. Neutral wiring is required for installation.

Customer feedback describes the timer as useful for applications such as porch lighting, while opinions on programming and ease of setup vary. Its scheduling choices are a practical fit for customers who want more control than a simple on/off routine.
