Choosing the right Push Button Switches is the first step toward building a control panel that is both safe and easy to operate. In India’s fast-paced industrial and commercial sectors, the “Human-Machine Interface” (HMI) needs to be foolproof. Whether you are a homeowner automating a gate, a school setting up a physics lab, or a commercial buyer managing an industrial plant, the physical switch is the most critical point of contact.
From Illuminated Push Button Switches that provide instant visual status to robust Industrial Push Button Switches designed for heavy-duty use, understanding the mechanical and electrical differences is key to a successful installation.
Illuminated Push Button Switches: Flush vs. Projected
Based on the Essen Deinki PB2-BW series (Image 1), illuminated switches come in two primary physical profiles. Both use LED Push Button Switches technology to ensure long-lasting brightness and low power consumption.
Flush Type (PB2-BW3)
The Flush Push Button Switch sits level with the mounting ring.
- Best For: “Start” or “Reset” functions where you want to prevent accidental activation. Because the button doesn’t stick out, it’s much harder to bump into it by mistake.
- Ordering Tip: Look for Type D (PCB2-BWL3) if you need the full assembly including the contact block.
Projected Type (PB2-BWL3)
The Projected Push Button Switch protrudes from the panel.
- Best For: Functions that need to be accessed quickly, even if the operator is wearing heavy industrial gloves. The raised profile makes it tactile and easy to locate without looking directly at the panel.
Selector Switches: 2-Position vs. 3-Position (Stay-Put)
Sometimes a simple “push” isn’t enough. For functions that require a permanent state change, Panel Mount Push Button Switches in a “Selector” format are used. These are “Stay-Put” switches, meaning they stay in the position you turn them to.
2-Position Stay-Put (PB2-BK2)
As seen in the blue actuator model (Image 2), these are ideal for simple binary choices.
- Common Uses: On/Off, Manual/Auto, or Local/Remote control.
- Reliability: These Electrical Push Button Switches provide a clear physical “click,” letting the operator know the state has been changed.
3-Position Stay-Put (PB2-BK3)
The red actuator model (Image 3) offers three distinct states.
- Common Uses: Forward/Off/Reverse or Hand/Off/Auto.
- Safety: The middle “Off” position acts as a neutral safety gap between two operational modes.
The Modular Ordering System: Decoding Types A, B, C, & D
One of the reasons Essen Deinki is a preferred Control Panel Push Button Switches provider is their modular design. You don’t always have to buy a whole new unit if only one part is needed.
| Type | Description | What’s Included |
| Type A | Actuator | Just the colored/shaped button or lever. |
| Type B | Body Assembly | The internal mechanical frame. |
| Type C | Actuator & Body | The complete mechanical front-end. |
| Type D | Complete Unit | Actuator + Body + Contact Block. |
Pro Tip for Indian Buyers: Always specify your Operating Voltage when ordering illuminated versions. Common Indian industrial standards include 24V, 110V, and 220V (AC or DC).
Customizing Your Switch: Colors and Contacts
To ensure your Metal Push Button Switch with LED fits your specific circuit, you must use the correct suffixes during purchase:
- Color Selection: * 1 (White), 3 (Green), 4 (Red), 5 (Yellow), 6 (Blue).
- Contact Configuration (*):
- 1: NO (Normally Open)
- 2: NC (Normally Closed)
- 3: NO + NO
- 5: NO + NC (The most versatile for industrial interlocks)
- C: 2NO + 2NC (For advanced automation logic)

Frequently Asked Questions
Q1. Can I use a 220V AC LED switch on a DC circuit?
No. You must mention the operating voltage and current type (AC or DC) while ordering. Using the wrong voltage will damage the LED module.
Q2. What is a “Stay-Put” switch?
A “Stay-Put” switch remains in the position you turn it to (like a selector switch). A “Momentary” switch springs back to its original position as soon as you let go.
Q3. Are these switches suitable for outdoor panels?
Yes, when mounted correctly in an IP-rated enclosure, the Essen Deinki switches provide excellent protection against environmental elements.
Q4. How do I choose between a Flush and Projected button?
Choose Flush if you want to prevent accidental presses. Choose Projected if you want the button to be very easy to hit quickly, especially in emergency-adjacent scenarios.
Conclusion: Build Better Panels with Essen Deinki
High-quality Push Button Switches are the foundation of any reliable control system. By choosing the right combination of Flush or Projected actuators and 2 or 3-position selectors, you ensure your machinery is both safe and efficient.
