1NO Momentary Flat Head Push Button Switch

Product Features

Modular 3-Part Architecture: Engineered with a split-body configuration comprising the actuator head, middle base, and detachable contact block. Combined with heavy-duty screw terminals, this design reduces wiring benchmarks and simplifies field maintenance for panel builders.

Extended Operational Longevity: Built for high-frequency industrial environments, delivering a mechanical durability threshold of 3 million cycles. Electrical endurance is customizable up to 1 million cycles to match specific control logic demands.

Anti-Rotation Alignment Boss: Features an integrated mechanical centering tab on the actuator head. This stabilization boss locks firmly into the panel cutout, eliminating switch rotation and structural shifting caused by severe machine vibration.

Industrial Ingress Protection (IP65 / IP66): Sealed to standard IP65 specifications for robust dust and liquid isolation. Optional IP66 encapsulation upgrades are available for deployment in severe washdown or heavily contaminated manufacturing zones.

Silver & Gold Plating Options: Equipped with high-purity silver-plated contacts for low-resistance conductivity. Optional gold-plated contact matrices can be specified to maintain signal integrity in low-current, low-voltage PLC circuits.

Factory-Direct Layout Options: Available in six standard signaling colors (Red, Green, Yellow, Blue, White, Black). Supports versatile wholesale circuit mapping with flexible normally open (NO) and normally closed (NC) block configurations.

FAQ

Q1: Can additional contact blocks be added to this 1NO momentary flat head push button switch?
Yes. The modular design allows additional contact blocks to be stacked onto the existing assembly — converting it from 1NO to 1NO1NC or 2NO configurations without replacing the head or frame. This is useful when your circuit requirements change after the panel is already assembled.

Q2: What is the silver-plated contact and why does it matter for industrial push button switches?
Silver-plated contacts have lower contact resistance and better resistance to oxidation compared to plain copper contacts. In switching applications with small loads — such as PLC inputs or relay coils — oxidized contacts can cause intermittent signals that are difficult to diagnose. Silver plating maintains consistent contact performance over the rated 3 million cycle lifespan.

Q3: Is this switch suitable for outdoor or washdown panel installations?
The standard IP65 rating protects against dust ingress and low-pressure water jets, making it suitable for most outdoor enclosures and light washdown environments. For high-pressure washdown applications such as food processing or marine installations, confirm whether IP66 or IP67 is required for your specific environment.

Q4: How do I specify the correct color when ordering this switch for a control panel?
Button color in industrial panels typically follows IEC 60947-5-1 conventions — for example, red for stop or emergency, green for start, yellow for reset or abnormal condition, and white or black for general functions. If your panel follows a different color convention or house standard, specify the color by name when ordering and we will confirm availability.
