PBS-11A 12mm Self-Locking Round Push Button Switch (Red) – 2-Pin Latching ON-OFF Power Switch for DIY Projects, Control Panels, and Toys

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.
