SMD-0603 6x6mm Tactile Switch: Technical Data Sheet
The SMD-0603 is a 6x6mm tact switch built for surface mounting. This datasheet lists its size, rating and life for design use. Engineers use it to plan compact PCB layouts with confidence.
What the SMD-0603 Tact Switch Is
The SMD-0603 is a standard 6x6mm tact switch. It uses surface-mount technology for fast automated assembly. Therefore, it fits consumer electronics, home appliances and office gear. In addition, cars and industrial panels use it for clear, momentary feedback.
Mechanical Specifications
The body measures 6.0mm by 6.0mm by 2.5mm. Therefore, it saves space on dense boards. However, real parts may vary by about ±0.1mm. Always check the official drawing before you design.
Mounting uses SMT and works with reflow solder. As a result, it suits high-volume lines. Pins come as 4-pin or 2-pin types. Moreover, the layout depends on the exact model you order.
Travel is 0.25mm with a ±0.1mm tolerance. This gives a crisp, clear click feel. Furthermore, actuation force is 160gf typical. The range runs 160±30gf. Thus, it balances feel with long service life.

| Body size | 6.0 × 6.0 × 2.5 mm |
| Actuation force | 160 gf (160 ± 30 gf) |
| Travel | 0.25 mm (± 0.1 mm) |
| Rated voltage | DC 12 V |
| Rated current | 50 mA |
| Contact resistance | ≤ 30 mΩ (initial) |
| Insulation resistance | ≥ 100 MΩ |
| Dielectric strength | 100 V DC/AC, 1 min |
| Operating temperature | -25 °C to +85 °C |
| Storage temperature | -30 °C to 80 °C |
| Mechanical life | 100,000 operations |
Electrical Specifications
Rated voltage is DC 12V for low-power devices. Current is 50mA for normal signal control. Therefore, the tact switch fits logic and interface circuits well. It does not switch power.
Contact resistance stays at or below 30mΩ at first. As a result, signal loss stays low. In addition, insulation resistance is 100MΩ or more. This blocks leakage between circuits. Furthermore, dielectric strength is 100V for one minute, which proves safe isolation.
Environmental and Durability Ratings
Operating temperature runs from -25°C to +85°C. Some models reach -35°C at the low end. Consequently, the tact switch works in varied sites. Storage temperature is -30°C to 80°C for safe keeping.
Mechanical life is 100,000 operations typical. Moreover, some versions last even longer. The part does not specify a fixed protection grade. However, certain 6x6mm types add basic dust proofing. They also suit lightly damp areas.
PCB and Soldering Design Notes
Follow the official mechanical drawing for pad size. Recommended pads are 1.2mm by 1.5mm. Spacing is 2.0mm, but verify per model. Therefore, wrong pads cause poor seating and failure.
Confirm the part supports reflow soldering. Otherwise, it may need hand soldering only. In addition, keep pin height low to avoid unstable mounting. Good layout protects it during use.
Appearance and Options
The button is usually black for a clean panel look. Furthermore, the standard part has no LED. If you need backlight, choose a dedicated model instead. This keeps the base part simple and low cost.
Frequently Asked Questions
What is the actuation force of the SMD-0603?
It is 160gf typical, with a range of 160±30gf. Therefore, it feels consistent across a production run.
Can the SMD-0603 be reflow soldered?
Yes, it supports SMT reflow assembly. However, confirm the exact model, since some types allow hand soldering only.
What is the rated voltage and current?
It is DC 12V at 50mA. As a result, it suits signal and low-power control, not main power paths.
Does the SMD-0603 have an LED?
No, the standard part has no backlight. In addition, the button is black by default. Pick a lit variant if needed.
