In industrial automation and electrical control systems, the efficiency of any machine depends heavily on how operators interact with it. Control panels may be the brain of operations, but push buttons and switches are the hands and senses that make everything work smoothly.
One of the most reliable and space-efficient solutions for panel builders is the PCB5 Series Twin-Push Button Switch.
In this guide, we’ll break down:
- Key features of the PCB5 Series
- Available types and ordering codes
- Installation and maintenance tips
- Why integrating Emergency Stop Switches is essential
What is the PCB5 Series Twin-Push Button?
The PCB5 Series is a dual-function push button switch that combines two actuators in one compact unit — typically:
- Green button (Start)
- Red button (Stop)
Instead of installing two separate 22.5mm push buttons, the PCB5 integrates both into a single housing, saving valuable panel space.
Key Features of the PCB5 Series
- Space-Saving Design
Panel space is always limited in MCC panels and distribution boards. The twin-push configuration reduces the number of panel cutouts, making it ideal for compact enclosures.
- Strong Plastic Mounting Bracket
Each unit comes with a durable plastic bracket that is:
- Lightweight
- Mechanically strong
- Designed for thousands of operations
- Ergonomic Operation
The buttons provide clear tactile feedback. Even in noisy factory environments, operators can feel the actuation and confirm the command instantly.
PCB5 Series Types & Ordering Codes
Understanding ordering codes helps during procurement and maintenance. Let’s explore the main variants.
PCB5-E8832 – Standard Flush Type
This is the base model of the series.
Configuration:
- Red flush button
- Green flush button
- Standard “O” (Stop) and “I” (Start) markings
Best for:
High-traffic areas where projecting buttons may snag clothing or equipment.
PCB5-EB842 – Projecting Red Type
In many industrial setups, stopping a machine quickly is more critical than starting it.
Configuration:
- Green flush button
- Red projecting button
Advantage:
The projecting red button can be located by touch alone. This improves response time during urgent situations.
PCB5-EBW 836 – Illuminated Flush Type (Amber Lens)
Modern panels require visual feedback.
Features:
- Two flush buttons
- Amber lens between them
Use Case:
The amber lens acts as a pilot light to indicate:
- Power ON
- Running status
- Fault condition
This reduces the need for a separate indicator lamp.
PCB5-EBW 846 – Illuminated Projecting Type
This is the most advanced model in the lineup.
Features:
- Projecting red button
- Green flush button
- Amber illuminated lens
Best for:
Complex machinery where both visual indication and quick tactile stop access are required.
Why Emergency Stop Switches Are Essential
While the PCB5 handles normal Start/Stop operations, it does not replace an Emergency Stop Switch.
A standard stop button performs a routine shutdown.
An Industrial Emergency Stop Switch:
- Cuts power instantly
- Locks in OFF position
- Requires manual reset
For machinery that poses any risk, an Emergency Stop Switch is mandatory under safety regulations.
As one of the trusted Emergency Stop Switch manufacturers in India, Essen Deinki emphasizes integrating proper safety components alongside operational controls.
Types of Emergency Stop Switches
Depending on your application, you may require:
Mushroom Head (Push-Pull)
Most common design. Easy to activate with palm pressure.
Key-Release Type
Prevents unauthorized machine restart.
Twist-to-Release
Ergonomic design that avoids accidental resets.
Safety Standards for Emergency Stop Buttons
When designing a panel with PCB5 switches, compliance is critical.
International standards such as ISO 13850 and IEC 60947-5-5 require:
- Red actuator
- Yellow background
- Positive opening operation
- Easy accessibility
Following these standards ensures compliance for domestic and export markets.
Installation Best Practices
To maximize performance and life:
Installation Tips
- Do not over-tighten the plastic bracket
- Use ferruled wire ends for secure connections
- Ensure proper alignment of illuminated lens models
Maintenance Checklist
Monthly
- Inspect for cracks or fading markings
Quarterly
- Test mechanical movement
- Check for dust or oil buildup
Yearly
- Retighten terminals if required
Regular inspection increases service life and prevents downtime.

Future of Control Panel Design
The industry is moving toward smart control panels integrated with PLC systems. Some systems now monitor push-button usage cycles for predictive maintenance.
However, no digital system can replace a hard-wired Industrial Emergency Stop Switch in critical situations.
Mechanical safety will always remain essential.
Conclusion
The PCB5 Series Twin-Push Button Switches offer:
Space efficiency
Reliable performance
Multiple configuration options
Integrated illumination choices
Whether you choose the standard PCB5-E8832 or the advanced PCB5-EBW 846, you are investing in dependable panel control.
But remember — operational control must always be paired with proper safety systems. Integrating certified Emergency Stop Switches ensures compliance, operator protection, and long-term reliability.

Frequently Asked Questions
Q1: Can PCB5 Series be used outdoors?
It is primarily designed for indoor use. For outdoor applications, use an IP65/IP67 rated enclosure.
Q2: What is the purpose of the amber lens?
It provides visual indication such as machine status, power, or fault signals.
Q3: Why is the red button sometimes projecting?
For ergonomic safety. It allows faster stopping by touch.
Q4: Is an Emergency Stop Switch mandatory?
Yes. Any machine with injury risk must have a certified Emergency Stop Switch.
Q5: Are contact blocks replaceable?
Yes. The modular design allows contact block replacement without changing the entire unit.
