SMD Tactile Switch, 3x6x2.5mm – TACT SWITCH SMD

Description

Here’s what makes a 3×6×2.5 mm SMD tactile switch useful, plus its electrical/mechanical properties:

• Form factor: Very compact surface-mount (SMD), with a footprint of about 3 mm × 6 mm and a low profile (2.5 mm height). Good for tight PCB designs.

• Mounting / Pins: 2-pin, typically SPST (single pole, single throw) momentary switch.

• Electrical rating: Usually around 50 mA at 12 V DC.

• Contact resistance: ~100 mΩ max.

• Operation force (“click feel”): ~160 gf (± tolerance) for many variants.

• Travel / stroke: ~0.25 mm (with tolerance) — how far the button moves when pressed.

• Durability: Many switches of this size are rated for ~50,000 actuations.

• Temperature: Operating range around –25 °C to +70 °C.

• Materials: Typically plastic body, stainless or silver-clad contacts, and a thermoplastic base.
