Mini Tact Switch TS263065 For Smart Wearable Devices

Below is an English product description for the Mini Tact Switch TS263065 intended for smart wearable devices. These are common industry/typical values for this class of ultra-low-profile SMT tact switches. For exact dimensions, curves, and specifications, please refer to the original manufacturer datasheet or share the supplier/brand.

Product overview

• TS263065 is an ultra-thin, miniature SMT tactile switch offering crisp actuation and compact footprint for space-constrained wearables such as smartwatches, bands, earbuds cases, and portable medical devices.
• The “263065” designation commonly corresponds to an approximate size of 2.6 × 3.0 × 0.65 mm (L×W×H), enabling slim device designs and dense PCB layouts.

Key features

• Ultra-low profile: height around 0.65 mm for sleek product form factors.
• Compact footprint: minimal board area for high-density placement.
• Distinct tactile feel: metal dome for clear click and fast return.
• Multiple operating forces: typical options 160/200/220/260 gf to balance feel and anti-mistouch.
• SMT compatible: supports standard reflow processes and automated assembly.
• Signal-level rating: typical 5–12 VDC, 10–50 mA for low-power inputs.
• Durable: typical life 200k–500k cycles depending on force and conditions.
• Environmental compliance: commonly RoHS/REACH; halogen-free versions may be available.

Mechanical and electrical (typical ranges)

• Type: top-actuated tactile switch; contact form: SPST-NO (normally open)
• Dimensions: approx. 2.6 × 3.0 × 0.65 mm (L×W×H)
• Travel: approx. 0.15–0.20 mm
• Operating force (OF): approx. 160/200/220/260 gf (±30–50 gf depending on version)
• Return force (RF): approx. 30–60 gf
• Contact resistance: ≤100 mΩ (initial)
• Insulation resistance: ≥100 MΩ (typical at 100 VDC)
• Dielectric strength: 100–250 VAC, 1 minute (no breakdown; per vendor spec)
• Electrical rating: 5–12 VDC, 10–50 mA (signal-level)
• Bounce time: ≤10 ms
• Operating temperature: -40 °C to +85 °C (typical), storage similar or wider depending on supplier
• Mechanical life: 200,000–500,000 cycles under rated load and proper installation

Materials and construction (common)

• Housing: high heat-resistant engineering plastic (e.g., LCP) suitable for reflow
• Dome: stainless steel metal dome
• Terminals: copper alloy with nickel underlayer; gold or silver surface plating per version
• Actuation interface: via product’s mechanical stack (plastic cap, metal or silicone pusher in the device)

Soldering and packaging

• Mounting: SMT
• Reflow: peak temperature typically ≤260 °C; recommend ≤2 reflow cycles and follow vendor profile; avoid pressing the switch during soldering
• Packaging: Tape & Reel, commonly 8 mm tape; typical 3,000–5,000 pcs per reel depending on supplier
• Moisture sensitivity: often low (e.g., MSL 1); verify with datasheet

Recommended applications

• Smartwatch/fitness band: side keys, function keys, reset keys
• TWS/earbud charging cases: pairing/reset buttons
• Portable medical/health monitors: power and mode selection
• Sports/fitness devices, miniature remotes, automotive trim micro-inputs

Protection and reliability guidelines

• Water/dust ingress: ultra-thin tact switches are generally unsealed; use silicone membranes, gaskets, or enclosure-level sealing to achieve IP protection (e.g., IP67)
• Side-load control: minimize lateral and off-center forces; use guides or hard stops to ensure centered actuation
• ESD/EMI: design discharge paths near openings; consider anti-static materials for button interfaces and proper shielding
• Thermal handling: allow cooling after reflow before pressing; avoid hot-state actuation to prevent damage
• Cleaning: prevent flux residues from entering the switch cavity; use low-residue processes and appropriate cleaning

PCB pads and layout (general guidance)

• Terminations: typically 2 electrical terminals plus 2 mechanical anchors (or only 2 electrical terminals); follow the manufacturer’s drawing
• Footprint: use recommended land pattern and spacing; consider larger pads for mechanical anchors to improve joint robustness
• Mechanical alignment: keep the pusher aligned to the switch center, ensure straight load path, and set pre-load/travel to meet feel and life targets

Ordering and customization

• Force options: e.g., TS263065-160/200/220/260 (example suffixes to distinguish operating force)
• Plating/environmental: options for gold/silver plating; halogen-free variants
• Packaging: “-TR” may indicate Tape & Reel (example)
• For full part-number rules, 3D STEP, 2D drawings (DXF/PDF), or reliability reports, please provide the brand/supplier.

Important notes

• Values above represent typical ranges for the “2.6 × 3.0 × 0.65 mm” ultra-thin SMT tact switch category. Exact ratings, life, forces, pad sizes, and reflow profiles vary by manufacturer and version.
• To avoid mismatch, please share the specific brand or datasheet. I can then provide precise dimensions, recommended footprint, reflow profile, test conditions, and ordering details.
