2. Core Product Features
1. Versatile Configurations for Every Application
- Momentary (Self-Reset): Spring-loaded design for temporary control signals (e.g., start/stop, jog functions)
- Latching (Self-Locking): Maintains position until manually reset, ideal for continuous control states
- LED-Illuminated: Transparent/colored lens with built-in LED for clear status indication (green/red available)
- Emergency Stop: Twist-to-release mushroom head design for quick, fail-safe shutdown in emergencies
- Selector Switches: 2/3-position rotary switches for mode selection (manual/auto, run/stop)
- Custom Symbols: Printable or laser-etched symbols (arrows, text, icons) for intuitive operation
2. Reliable Electrical Performance
- Contact Configuration: Standard 1NO1NC (1 Normally Open + 1 Normally Closed) contacts for flexible circuit integration
- High Sensitivity Contacts: Silver alloy contacts ensure low contact resistance, fast response, and stable conductivity
- Wide Compatibility: Rated for 250V AC / 30V DC, supporting most low-voltage control circuits
- Long Mechanical Life: Over 1,000,000 operations for momentary switches; 500,000 operations for latching/emergency stop types
3. Robust Industrial-Grade Construction
- 22mm Standard Panel Mount: Universal hole size compatible with standard control panels worldwide
- IP65 Protection Rating: Dust-tight and water-resistant housing, suitable for indoor/outdoor industrial environments
- Durable Housing: High-grade flame-retardant plastic and metal components resist impact, heat, and aging
- Vibration-Resistant Design: Secure locking mechanism prevents accidental actuation in high-vibration environments
4. User-Friendly Installation & Operation
- Quick Wiring: Screw-type terminals for secure, reliable wire connections (supports copper conductors)
- Tool-Less Assembly: Modular design allows quick replacement of contacts, lenses, and buttons
- Ergonomic Operation: Smooth tactile feedback and clear visual cues reduce operator error
- Compact Footprint: Space-saving design optimizes panel layout for multi-switch setups

6. Frequently Asked Questions (FAQ)
1. What is the difference between momentary and latching LA38 switches?
- Momentary (Self-Reset): Returns to the default state when released, used for temporary signals (e.g., start buttons).
- Latching (Self-Locking): Stays in the pressed position until manually reset, used for continuous control (e.g., power switches).
2. Can I customize the symbols or colors on the LA38 switches?
Yes! We offer customizable symbols (arrows, text, icons) and colors (red/green/black/yellow) for both illuminated and non-illuminated models to match your equipment’s requirements.
3. Are the LA38 switches waterproof and dustproof?
Yes. The LA38 series features an IP65-rated front panel, making it dust-tight and resistant to water splashes. It is suitable for use in industrial environments, outdoor equipment, and washdown areas.
4. What does “1NO1NC” mean, and is it standard for all models?
“1NO1NC” means each switch has one Normally Open (NO) and one Normally Closed (NC) contact, allowing flexible circuit integration (e.g., sending signals to both start and stop circuits simultaneously). This configuration is standard for most LA38 models.
5. What LED voltage options are available for illuminated LA38 switches?
We offer LED options for 12V, 24V, and 220V, compatible with most common control system voltages. Custom LED colors (red/green/amber/blue) are also available upon request.
6. How do I install the LA38 push button switch?
Installation is simple:
- Drill a 22mm hole in the control panel.
- Insert the switch body from the front.
- Secure it with the included mounting nut.
- Wire the NO/NC contacts to your control circuit using the screw terminals.
7. Are the emergency stop LA38 switches compliant with safety standards?
Our emergency stop switches feature a twist-to-release mushroom head design, meeting basic safety requirements for quick shutdown. They are suitable for integration into safety circuits, though we recommend combining them with certified safety relays for critical applications.
