Hot-Sale DIP Micro Tact Switch For Smart Home Systems

A high-reliability, through-hole (DIP) micro tactile switch designed for smart home hubs, wall panels, remote controllers, and sensor endpoints. It delivers crisp tactile feedback, low contact resistance, and long mechanical life. Optimized for low-current signal inputs and compatible with common enclosure and panel structures to minimize false triggers and contact bounce.

Key Features:

• Reliability: Long-life metal dome structure, mechanical life 100k–1,000k cycles (varies by model)
• Tactile feel: Multiple operating forces available (160/260/320 gf) with clear click and rebound
• Easy assembly: DIP through-hole mounting for wave solder or hand solder; straightforward maintenance
• Low bounce: Low contact resistance and short bounce time for clean signals
• Eco-friendly: Housing flame rating UL94 V-0; RoHS and REACH compliant
• Customizable: Height, cap color, operating force, and terminal plating customizable; logo and OEM options supported

Typical Applications:

• Smart home gateways/central controllers
• Smart wall panels and scene controllers
• Smart door locks/doorbells and HMI keys
• Thermostats, AC panels, air purifiers
• Remote controls and function keys on home sensors

• Operating temperature: -25°C to +85°C (storage -40°C to +85°C)
• Protection: IP40 standard; consult for enhanced dust/moisture protection

Construction and Materials:

• Housing: PA66/PBT, UL94 V-0 flammability
• Terminals: Phosphor bronze/brass, nickel or silver plated (options)
• Dome: Stainless steel
• Contacts: Silver alloy; optional gold plating for low-current signal optimization
• Cap: PC/PBT, multiple colors available (black/white/gray/custom)

Dimensions (common 6×6 series example):

• Body size: approx. 6.0 × 6.0 mm
• Pins: 4-pin (two parallel terminal pairs, same polarity)
• Mounting: DIP through-hole; footprint follows standard 6×6 tact layout
• Height options (with actuator/cap): approx. 4.3 / 5 / 7 / 8 / 9 / 10 / 12 / 13 mm (model dependent)
• Footprint and pin spacing: standard 6×6 tact footprint; PCB land pattern and STEP files available

Installation and Soldering Guidelines:

• Wave solder: Peak ≤260°C, dwell ≤3 s; avoid repeated high-temperature cycles
• Hand solder: Iron at 350°C, contact time ≤3 s per pin
• Cleaning: Use IPA spot cleaning; avoid solvent immersion
• Mechanical stress: Do not apply lateral force or off-center pressing during assembly
• Storage: Keep dry and sealed; use promptly after opening to prevent moisture uptake

Quality and Certifications:

• RoHS and REACH compliant
• Manufacturing system: ISO 9001
• Housing flammability: UL94 V-0
• Batch consistency report and life test data available upon request

Packaging and Supply:

• Packaging: Bulk bag/tray/tube (model dependent); typical 1,000–5,000 pcs per carton
• Lead time: Standard models 5–12 business days; custom models based on engineering confirmation
• MOQ: Typically 1,000 pcs; samples and small runs negotiable
• Samples: Free samples available (project details required)

Part Numbering and Ordering Example:

• Format: HMT-6x6-DIP-[Force]GF-[Height]H-[Plating]-[CapColor]
• Example: HMT-6x6-DIP-260GF-7H-AG-BLK
  • 6×6 body, DIP through-hole
  • 260 gf operating force, 7 mm height
  • Terminal silver plating (AG), black cap (BLK)
  • Gold plating option: AU (recommended for <10 mA signal applications)

Selection Tips:

• For ultra-low current signals (<10 mA) and minimal contact resistance variation, choose gold-plated contact/terminal versions.
• For higher resistance to accidental presses, select 260 gf or 320 gf force.
• If longer travel or softer feel is preferred, select 160 gf.
• For panels requiring dust or moisture mitigation, add a sealing cap or design-in gasketed structures.

FAQ:

• Can height and cap color be customized? Yes. Provide target panel thickness and aesthetic requirements.
• Suitable for high-voltage/high-current circuits? Not recommended. Designed for low-level signal inputs to MCU/logic.
• Is there an SMD version? Yes. A matching 6×6 SMD tactile switch is available.
