XUNPU TS-1088-AR02016

FAQ du produit

• 1. What are the key electrical limits and physical dimensions of the TS-1088-AR02016?
  The TS-1088-AR02016 is a miniature SPST normally-open tactile switch for low-power signal applications. It is rated for a maximum switching voltage of 12V DC and a contact current of 50mA, making it suitable for logic-level circuits rather than direct power switching. The body measures 4.0mm × 3.0mm with a 2.0mm height, optimised for high-density PCB layouts. Its compact form and approximately 160gf (1.6N) actuation force suit handheld electronics, IoT devices, and control panels where space is tight.
• 2. Can this switch safely interface with Arduino, ESP32, or Raspberry Pi GPIO circuits?
  Yes. The TS-1088-AR02016 works with 3.3V and 5V GPIO systems used on Arduino, ESP32, STM32, and Raspberry Pi. As a momentary SPST input it is typically wired with internal or external pull-up resistors (commonly 10kΩ) to produce clean digital transitions, and its ~160gf actuation force gives stable tactile feedback that reduces accidental presses. It must not be used to switch inductive or high-current loads above its 50mA rated limit.
• 3. How reliable is the TS-1088-AR02016 in long-term mechanical use?
  The TS-1088-AR02016 is rated for approximately 100,000 switching cycles under standard operating conditions and operates from −30°C to +80°C, maintaining stable contact resistance and insulation during normal use. The internal dome provides a consistent actuation force of about 160gf for predictable tactile response. Long-term reliability depends heavily on solder quality and mechanical alignment, since excessive enclosure pressure or misalignment can reduce both feel and lifespan.
• 4. What packaging format and sourcing options are typically available for procurement?
  The TS-1088-AR02016 is supplied on tape-and-reel for automated SMT assembly, with about 4,000 pieces per reel (SPQ). Smaller quantities are often available for prototyping and low-volume evaluation. For volume production, ordering full reels ensures compatibility with pick-and-place machines and consistent feed reliability. Confirm exact MOQ and availability per the current LCSC listing, as stock can vary by region.
• 5. What PCB layout and assembly practices ensure correct operation of this switch?
  Use accurate SMD pad alignment on the 4.0mm × 3.0mm footprint for stable mechanical seating during reflow, with standard lead-free profiles and peaks typically limited to 260°C for under 10 seconds. Place the switch near the enclosure actuation point while ensuring no permanent mechanical preload is applied to the actuator. Excess force from the enclosure can reduce tactile feel and shorten the rated 100,000-cycle life, and poor pad geometry can lead to tombstoning or weak joints.
