Illuminated Capacitive Touch Switches SF25BB Series

Product Overview

SF25BB Series is an industrial‑grade capacitive touch sensor switch engineered for high‑reliability human‑machine interface applications. The product employs non‑contact capacitive sensing technology, which detects changes in the human body's electric field to achieve precise triggering—completely eliminating the physical wear issues associated with traditional mechanical pushbuttons. It features a built‑in full‑color RGB LED illumination system that supports multi‑color status indication and breathing light effects. Combined with a stainless steel metal housing and an IP65 protection rating, the SF25BB maintains excellent touch sensitivity and visual clarity even in harsh industrial environments.

Technical Parameters

Key Features

1. Zero Mechanical Wear – Extended Service Life
By eliminating traditional spring and contact structures, the all‑electronic sensing method means switch life is no longer limited by mechanical fatigue – ideal for high‑frequency operation scenarios.

2. Fully Sealed Metal Protection System
SUS stainless steel housing combined with a precision waterproof structure delivers an IP65 rating on the front face, effectively resisting dust ingress and low‑pressure water jets – suitable for damp and dusty industrial environments.

3. Intelligent Light‑Effect Interactive Feedback
Integrated RGB LED module allows customisation of standby and trigger colours according to equipment status (e.g., blue breathing glow in standby, solid green on activation), enabling intuitive visualisation of the equipment’s operating state.

4. Dual‑Mode Logic Output
Supports both Momentary and Alternate (latching) output modes, selectable via hardware configuration to meet different control logic requirements without the need for additional programming.

5. Wide‑Voltage Compatible Design
Available in two voltage variants: 5V DC and 7–24V DC, covering the majority of power supply scenarios – from embedded microcontroller systems to industrial PLC control cabinets.

Applications

1. Medical Equipment：

• Operating room control panels, disinfection equipment interfaces – meeting high cleanliness and touchless operation requirements.

2. Industrial Automation：

• CNC machine operator stations, production line control cabinets – resistant to cutting fluid and metal dust ingress.

3. Smart Home：

• Kitchen appliance panels, bathroom mirror‑front controls – splash‑proof and easy to clean.

4. Security Systems：

• Access control call panels, alarm trigger devices – metal housing provides vandal‑resistant protection.

5. Broadcast & AV Equipment：

• Studio lighting desks, live broadcast control consoles – RGB lighting effects enhance operational visibility.

6. Rail Transit：

• Passenger information systems inside train carriages, driver’s cab control panels – capable of withstanding vibration and temperature variation environments.
