Description

Black Waterproof PBS-33A 12MM 2PIN Mini Round Push Button Switch with lock

The PBS-33A 12MM Waterproof Switch with Lock in black is a compact and durable push button switch designed for a wide variety of electronic and industrial applications. With a 12mm mounting diameter, it fits neatly into control panels and project enclosures. Its IP-rated waterproof design ensures protection against dust, moisture, and splashes, making it ideal for outdoor or damp environments.

This switch features a locking mechanism, meaning it stays in the pressed (ON) or released (OFF) position until pressed again—perfect for power control, device switching, and machinery operation. The black round body gives it a clean, professional appearance, while the 2-pin connection allows for easy integration into most low-voltage DC circuits. It’s a reliable choice for DIY projects, automotive use, and industrial control systems.
