TS-2301A Micro Tact Switch — 2‑Pin SMT Tactile Switch Product Overview
The TS-2301A micro tact switch is a miniature, side‑actuated SMD tactile switch designed for high‑density PCB layouts where space is extremely limited. With a compact footprint of just 3.0×2.6mm and a height of 1.4mm, this micro tact switch SMD 2 pin fits seamlessly into wearables, hearing aids, IoT sensors, handheld meters and portable consumer devices. The 2‑pin surface‑mount design supports standard reflow soldering processes and ensures consistent, reliable tactile feedback over a lifetime of 200,000 cycles, making it a trusted choice for high‑volume production.
Engineers choose this 2 pin surface mount tact switch PCB solution because it eliminates through‑hole drilling, reduces assembly steps and offers a crisp actuation feel despite its tiny size. The phosphor bronze contacts with gold plating provide stable low contact resistance, while the high‑temperature LCP housing withstands lead‑free reflow profiles up to 260°C.

Micro Tact Switch SMD 2 Pin — Frequently Asked Questions
Can I get a free sample of the TS-2301A for prototyping?
Yes. We offer free samples to qualified engineering and product development teams. Please email sales@vistarelectronics.com with your company name, project application and the part number TS-2301A. Standard MOQ for production orders is 1,000 pieces.
What is the difference between the standard and IP67 version?
The IP67 version adds a transparent silicone seal over the actuator, providing complete protection against dust ingress and temporary immersion in water (1 m depth, 30 min). The electrical and mechanical specifications remain identical. This version is recommended for outdoor, medical or industrial applications exposed to moisture.
Is the TS-2301A compatible with lead‑free reflow soldering?
Absolutely. The LCP housing and gold‑plated terminals are designed to withstand peak reflow temperatures of 260°C for up to 10 seconds, fully compliant with JEDEC J‑STD‑020. The switch is also moisture sensitivity level (MSL) 1, meaning no pre‑bake is required before soldering.
What actuation forces are available besides 160gf?
The standard catalog part is 160 ±30gf, but we can produce variants with 100gf or 260gf upon request (subject to MOQ). Please discuss your requirements with our engineering team for a custom solution.
