3.45mm SMT tactile switch 250gf DW-TS-S060183A-01TR-01 is a compact top-actuated surface-mount tact switch rated at 12 VDC / 50 mA. It features 250±50 gf operating force, 0.15±0.10 mm travel, 50,000-cycle minimum life, silver-plated metal components, tape-and-reel packaging, and RoHS-compliant construction.
Applications: Control panels, embedded electronics, consumer electronics, communication equipment, instrumentation, handheld devices, smart products, and PCB push-button interfaces.
Highlights: 3.45 mm height option; SMT mounting; top actuation; 250±50 gf operating force; 12 VDC / 50 mA maximum rating; ≤100 mΩ contact resistance; ≥100 MΩ insulation resistance; 250 VAC/1 minute withstand voltage; 0.15±0.10 mm travel; ≥50,000 cycles; LCP actuator; PPA base; silver-plated brass cover; silver-plated stainless-steel spring; silver-plated phosphor-bronze contact component; tape-and-reel packaging; RoHS compliant.
3.45mm SMT tactile switch 250gf DW-TS-S060183A-01TR-01 is a compact top-actuated momentary switch designed for surface-mount PCB control and user-input applications. The Dragon Well drawing confirms the A height option at 3.45 mm, tape-and-reel packaging, and operating-force code 01 = 250±50 gf.
The switch is rated at 12 VDC / 50 mA maximum. Electrical performance includes 100 mΩ maximum contact resistance, 100 MΩ minimum insulation resistance, and 250 VAC dielectric withstand voltage for 1 minute. The drawing specifies a minimum mechanical/electrical operating life of 50,000 cycles and actuator travel of 0.15±0.10 mm.
This 3.45mm SMT tactile switch 250gf uses an LCP actuator, PPA base, and plated metal components selected for compact tactile-switch construction. The cover is made from 0.2 mm brass with silver plating, the spring element is silver-plated stainless steel, and the contact component is 0.15 mm phosphor bronze with silver plating. The drawing also provides the recommended PCB footprint for SMT assembly.
The part-number structure identifies two operating-force options within the family: 01 = 250±50 gf and 02 = 160±50 gf. This specific DW-TS-S060183A-01TR-01 version therefore uses the 250±50 gf force option. TR identifies tape-and-reel packaging for automated production.
The 3.45mm SMT tactile switch 250gf is suitable for control panels, consumer electronics, communication equipment, handheld devices, embedded controls, instrumentation, smart devices, and other PCB-mounted push-button interfaces. Comparable SMT tactile-switch families also commonly use 12 VDC / 50 mA ratings and momentary push-button operation.
