Push Button Waterproof Self-Reset Switch Round Lockless PBS-33B 12mm

The PBS-33B Waterproof Push Button Switch is a high-quality self-reset momentary switch designed for electronic control systems and industrial applications. The switch operates using a Push-to-ON (OFF-ON) mechanism, automatically returning to its original state after release.

Its 12mm mounting hole size allows easy installation on control panels, electronic enclosures, and equipment housings. The waterproof construction enhances durability and reliability in environments exposed to moisture, dust, and frequent usage.

The switch is available in multiple colors including red, yellow, green, blue, white, and black, making it suitable for color-coded control systems and user interfaces.

Built for long-lasting performance, the PBS-33B supports more than 10,000 operating cycles and provides stable electrical conductivity with low contact resistance.
