Product Description The PBS-11A is a compact, self-locking round push button switch designed for easy panel integration. Unlike momentary switches that release immediately, this "Latching" model stays depressed (ON) after the first click and returns to the original position (OFF) only after a second click. This makes it an excellent choice for the technicians at Robogears Pvt Ltd when building power toggles for battery-operated gadgets, LED indicators, or mode selectors in custom project boxes. The vibrant red button and threaded body ensure it is both easy to locate and secure to mount.

Key Highlights

  • Self-Locking Action: Provides a reliable mechanical "memory," staying in the set state without constant user pressure—perfect for master power switches.

  • Easy Panel Mounting: The 12mm threaded body fits into standard circular drill holes and comes with a hex nut and washer for a firm, vibration-resistant fit.

  • Space-Efficient Design: Its small circular footprint is ideal for high-density control panels where rectangular rocker switches might be too large.

  • Durable Plastic Construction: Made from high-quality, flame-retardant plastic with silver-plated brass terminals for consistent electrical conductivity.

  • Versatile Voltage Support: While rated for AC, it is frequently used in DC circuits (up to 24V) for robotics and automotive DIY hobbyist applications.

Technical Specifications

  • Contact Resistance: $\leq 50$ m$\Omega$

  • Insulation Resistance: $\geq 100$ M$\Omega$

  • Dielectric Strength: 1500V AC for 1 minute

  • Operating Temperature: -25°C to +85°C

  • Mechanical Life: $\geq 50,000$ Cycles

  • Total Length: ~30mm (including pins)

Prototyping & Installation Tip

Installation Strategy: When installing this switch at your Pimpri workshop:

  1. Use a 12mm drill bit for a snug fit.

  2. Since it is a 2-pin SPST switch, it simply acts as a gate. Wire it in series with the Positive (+) line of your battery or the Phase line of your AC supply.

  3. For the most professional finish in a 3D-printed or acrylic enclosure, tighten the hex nut from the inside so that only the red dome and the thin black rim are visible on the exterior.

Wiring Safety: Always use heat-shrink tubing over the solder joints. Because the pins are relatively close together on a 12mm switch, this prevents accidental shorts if the wires are pulled or twisted during assembly.
