In this guide, we’ll explore the features, models, specifications, and applications of the PB2 series—so you can make an informed choice for your next project.
Key Features of the PB2 Push Button Switches
1. Durable Plastic Enclosure
The PB2 control stations come in strong plastic housings that balance lightweight design with exceptional durability.
Available in yellow and black for high visibility, or grey and black for a more professional look.
Resistant to corrosion and chemicals, making them ideal for harsh environments.
Compact design:
1-way models: 68 mm × 68 mm footprint, 51 mm height.
Easy to install on different panels and surfaces.
This makes them perfect for factories, processing plants, and outdoor setups.
2. IP65 Protection – Dust & Water Resistant
The PB2 series comes with an IP65 protection rating, ensuring:
Dust-tight performance – complete protection against airborne dust and particles.
Water resistance – withstands low-pressure water jets, splashes, or light rain.
This makes them suitable for:
Food processing plants with frequent washdowns.
Outdoor pump stations.
Dust-heavy industries like construction and milling.
With IP65 protection, you can rely on these switches to last longer and reduce maintenance issues.
3. Compliance with International Standards
The PB2 series meets IS: 13947 (part 5/sec.-1) and IEC: 947-5(1) standards. It also carries the CE mark, making it compliant with EU safety and environmental directives.
This guarantees:
Safe and reliable operation.
Global acceptance for international projects.
Long-term trust in quality and performance.
Different PB2 Models and Their Applications
The PB2 series isn’t one-size-fits-all. It comes in 1-way, 2-way, and 3-way enclosures to suit different control needs.
1-Way Push Button Control Station (PC-01P / PC-01PY)
Compact design for a single 22.5 mm button.
Ideal for:
Start/stop functions.
Emergency stop button.
On/Off control for small equipment.
2-Way Push Button Control Station (PC-02P)
Designed for two 22.5 mm buttons.
Typical uses:
Start/Stop for conveyor systems.
Open/Close for gates.
Up/Down control for hoists.
3-Way Push Button Control Station (PC-03P)
Fits three 22.5 mm buttons.
Great for more complex operations:
Multi-stage machines (Manual/Auto/Stop).
Crane control (Hoist Up/Down/Stop).
Centralized machine control.
Why Push Button Switches Matter in Modern Industry
Push Button Switches are the backbone of machine control systems. A single press changes the state of a circuit, sending commands to PLCs or motor starters.
The PB2 series ensures reliability with:
Durable enclosures that withstand industrial stress.
IP65 protection for longer life.
Modular design (22.5 mm standard holes) for compatibility with buttons, pilot lights, buzzers, or selector switches.
This flexibility allows engineers to build custom control solutions with ease.
Practical Applications of the PB2 Series
PB2 Push Button Switches are highly versatile and can be used for:
Emergency Stop Stations – Yellow enclosures provide instant visibility.
Manual Machine Control – Override automation, jog machines, or test equipment.
Signaling & Alarms – Add illuminated buttons or lights for clear machine status.
Motor Control – Start, stop, or reverse motors with ease.
Conclusion
The Essen PB2 Series Push Button Switches offer the perfect mix of durability, safety, and flexibility for modern industries. Whether you need a simple 1-way switch for a motor start or a 3-way control station for complex operations, the PB2 series provides a reliable solution.
By choosing these switches, you get:
Long-lasting performance in tough environments.
Compliance with international safety standards.
Easy installation and customization.
If you’re building or upgrading a control system, the PB2 series is a smart, dependable choice that ensures both safety and efficiency.
