When selecting industrial push button switches for control panels, machinery, or automation systems, B2B buyers need precise, verifiable specifications. This blog focuses on a 22mm metal push button switch series that meets demanding environmental and electrical requirements.
Below are the key technical parameters, formatted for easy integration into engineering documentation.
1. Mounting & Mechanical Dimensions
The switch is designed for standard panel mounting.
Mounting hole diameter: 22 – 22.2 mm
Thread size: M22 × 1
Key mechanical tolerances:
6.2 ± 0.05 mm
25 ± 0.2 mm
12.3 ± 0.2 mm
Pin dimensions: 2.8 × 0.5 mm (switch pin and lamp pin)
These tight tolerances ensure reliable fitting in high-vibration environments.
2. Electrical Ratings
The switch supports both AC and DC applications, with clear separation between switching capability and heating current.
| Parameter | Rating |
|---|---|
| Switching voltage | 1.5V – 250V AC/DC |
| Current rating (switching) | AC: 15A, DC: 10A |
| Rated heating current (Ith) | 5A / 250V AC |
✅ The 5A rated heating current is a critical parameter for continuous load applications, as it differs from momentary switching current.
3. Environmental & Protection Ratings
This series is built for harsh industrial environments.
Waterproof rating: IP67 (at the button end)
Ambient temperature range: –30°C to +85°C
IP67 protection ensures the switch remains dust-tight and withstands temporary immersion in water, making it suitable for outdoor or wash-down applications.
4. Materials & Construction
Material selection directly impacts durability, corrosion resistance, and electrical performance.
| Component | Material |
|---|---|
| Housing | SUS304 stainless steel / Brass nickel-plated / Aluminum alloy anodized |
| Button (key) material | PC & SUS316 |
| Contact material | Silver tin oxide alloy |
| Base material | Optional (engineering plastic or other) |
Silver tin oxide alloy contacts provide lower contact resistance and better anti-welding properties than pure silver, especially under inductive loads.
5. Operating Mechanism & LED Options
Work form: Self-locking or self-resetting (momentary) – optional
LED illumination colors: Red, green, yellow, blue, white
Customization available: Two-color, three-color, or multi-color
The switch working status is clearly defined:
Button pressed down: circuit closed (or latched in self-locking mode)
Button ejected: circuit open
6. Dielectric & Insulation Strength
Although exact values are application-specific, the product family supports configurable dielectric strength to meet different safety standards. Buyers should confirm required insulation ratings with the manufacturer.
Conclusion for B2B Buyers
This 22mm metal push button switch offers:
IP67 waterproof rating
Wide operating temperature (–30°C to +85°C)
Silver tin oxide contacts for reliable switching
Multiple housing materials (SUS304, brass nickel-plated, anodized aluminum)
Flexible LED color options
For control panel builders, industrial equipment manufacturers, and automation integrators, these verified specifications support both SEO (search engines) and GEO (generative AI) discovery.
