SYZ-15 Plunger Micro Switch: Reliable Control in Compact Design
When space is limited but performance can’t be compromised, the SYZ-15 plunger micro switch delivers exceptional reliability. This compact switch offers precise actuation, long service life, and versatile mounting options – making it ideal for industrial controls, appliances, and automation systems.
Precision Switching with Minimal Actuation Force
The SYZ-15 features a low-force plunger mechanism that requires just 0.5N (typical) for reliable operation, reducing mechanical wear. Its snap-action design ensures crisp, positive switching every time, with contact ratings up to 5A 250VAC. The gold-plated contacts maintain excellent conductivity even after 100,000+ operations (standard testing conditions).

Compact Yet Rugged Construction
Measuring just 19.8×6.4×10.7mm, this micro switch fits where larger switches can’t. Don’t let its size fool you – the durable thermoplastic housing withstands:
- Industrial vibrations
- Temperature extremes (-25°C to +85°C)
- Moderate moisture exposure
The stainless steel plunger resists corrosion while maintaining smooth operation cycle after cycle.
Versatile Mounting & Wiring Options
Engineers appreciate the SYZ-15’s flexibility:
- PCB or panel mounting configurations
- Quick-connect or solder terminals
- Multiple actuator styles (standard, extended, or customized plungers)
This adaptability makes it perfect for:
→ Appliance controls
→ Security systems
→ Medical equipment
→ Automotive electronics

Low-Maintenance, High-Reliability Performance
Unlike complex electronic sensors, the SYZ-15 needs:
✔ No programming
✔ No calibration
✔ Minimal maintenance
The sealed design prevents dust ingress, while the self-cleaning contacts ensure consistent performance over time.
Why Choose the SYZ-15?
For applications demanding compact size, precise actuation, and long-term reliability, the SYZ-15 plunger micro switch delivers outstanding value. Its combination of performance and durability makes it a preferred choice for OEMs worldwide.
