In industrial automation and electrical systems, even the smallest components play a critical role. Push Button Switches are a perfect example. They form the direct connection between an operator and a machine—starting processes, stopping operations, or triggering emergency actions. Because of this, reliability and safety are non-negotiable.
In this blog, we explore the design, specifications, and performance of Push Button Switches used in the PB2 Series Control Stations by Essen Deinki, and understand why they are trusted in demanding industrial environments.
What Is a Push Button Control Station?
A push button control station is more than just a housing—it is a protective enclosure designed to safely mount push button switches and electrical contacts. It ensures smooth operation while shielding internal wiring from dust, moisture, and mechanical stress.
The PB2 Series Control Stations are engineered to offer:
- Easy installation
- Operator safety
- Long-term durability in harsh conditions
Design & Build: Durable Plastic Enclosure
Modern industrial setups require components that are both tough and visually clear. The PB2 series uses a high-quality plastic enclosure, offering several advantages:
Key Benefits of Plastic Enclosures
- Corrosion Resistance: Ideal for humid or chemically active environments
- Electrical Insulation: Reduces the risk of electric shock
- Lightweight & Durable: Easier to install without compromising strength
Color Coding for Safety & Identification
To support clear visual communication on the shop floor, the PB2 series comes in two color options:
- Yellow Top with Black Base: Commonly used for emergency stop or high-alert functions
- Grey Top with Black Base: Ideal for standard start/stop or directional controls
Technical Specifications: Precision That Matters
Standard 22.5 mm Mounting Cutout
The PB2 series uses a standard Ø22.5 mm cutout, making it compatible with a wide range of globally accepted push button switches and pilot lights. This ensures easy replacement and flexible system design.
Available Configurations & Dimensions
The PB2 series is modular and available in multiple “ways,” depending on how many switches or indicators you need.
| Configuration | Dimensions (L × W × H) | Ordering Code |
| 1-Way (Yellow/Black) | 68 × 68 × 51 mm | PC-01PY |
| 1-Way (Grey/Black) | 68 × 68 × 51 mm | PC-01P |
| 2-Way (Grey/Black) | 105 × 68 × 51 mm | PC-02P |
| 3-Way (Grey/Black) | 135 × 68 × 51 mm | PC-03P |
Tolerance: ±0.5 mm
This ensures accurate alignment when multiple control stations are mounted side by side.
Performance & Protection: IP65 Rated
Industrial environments can be dusty, wet, and unpredictable. That’s why the PB2 series control stations are rated IP65.
What IP65 Means
- Dust-Tight: Prevents dust and particles from entering the enclosure
- Water Jet Resistant: Withstands low-pressure water jets from any direction
This makes the PB2 series suitable for:
- Manufacturing plants
- Food processing units
- Pharmaceutical facilities
- Outdoor industrial installations
Compliance with International Standards
Safety and performance are backed by compliance with recognized standards:
- IS 13947 (Part 5 / Section 1) – Indian standard for low-voltage control gear
- IEC 947-5-1 – International safety and performance standard
- CE Certification – Meets European safety, health, and environmental requirements
Installation & Mounting Made Easy
Mounting Hole Details
- 1-Way & 2-Way Units: Mounting hole centers at 54 mm
- Screw Compatibility: Ø4.1 mm or Ø4.3 mm screws
This ensures a secure fit, even in high-vibration environments where buttons are frequently operated.
Cable Entry with Knockouts
Pre-molded knockouts allow flexible cable entry from the sides or bottom. When used with proper cable glands, the IP65 protection remains intact.
How to Choose the Right Control Station
When selecting a PB2 series control station, consider:
- Number of Controls: Start/Stop (2-Way) or Forward/Reverse/Stop (3-Way)
- Visual Importance: Yellow for emergency functions, grey for standard operations
- Space Availability: Compact 68 mm width is ideal for tight installations
Conclusion: A Reliable Interface You Can Trust
Though often overlooked, push button switches and their enclosures are the backbone of safe and efficient machine operation. The PB2 series control stations combine robust design, precise engineering, IP65 protection, and global compliance to ensure dependable performance in real-world industrial conditions.
By choosing high-quality control stations from Essen Deinki, you invest in:
- Operator safety
- Machine longevity
- Long-term operational reliability
When every press matters, confidence starts with the right control station.
