When it comes to heavy-duty industrial applications like automotive start systems and lift equipment, reliability, durability, and waterproof performance are non-negotiable. Our 22A Series Waterproof Metal Push Button Switch (available in 16/19/22mm mounting hole sizes) checks all these boxes—here’s why it’s the top choice for B2B buyers in automotive and industrial sectors.
Core Features for Industrial-Grade Performance
Designed to withstand harsh environments, this switch combines robust construction with precision engineering:
- Deep Waterproofing: IP67 (customizable to IP68) rating ensures protection against dust, splashes, and even temporary submersion—critical for outdoor/under-hood automotive use.
- Durable Build:
- Housing: SUS304 stainless steel, brass nickel-plated, or aluminum alloy anodized (corrosion-resistant for long-term use).
- Key Material: PC + SUS316 stainless steel (scratch-resistant, ergonomic large button design).
- Environmental Sealing: Built-in waterproof ring + brass nut for a tight, secure fit.
- Electrical Reliability:
- Gold-plated pins + large silver contacts (low contact resistance ≤50mΩ, high conductivity).
- Built-in back resistor (prevents short circuits in pre-wired setups).
- Versatile Functionality:
- Maintained/Momentary Options: Choose between latching (maintained) or self-resetting (momentary) operation to match your system’s needs.
- Multi-Color LED Options: 1.8V/3.3V/6V/12V/24V lamp beads (red, yellow, green, etc.) with high-brightness, large-aperture illumination for clear status visibility.
- AC/DC Universal Compatibility: Works with both alternating and direct current systems.
Technical Specifications (Tailored for Industrial Applications)
Below are the critical parameters that make this switch suitable for automotive start and lift systems:
| Parameter | Details |
|---|---|
| Mounting Hole Diameter | 16-16.1mm, 19-19.1mm, 22-22.1mm (fits standard industrial panel cutouts) |
| Switching Voltage | 1.5-250V AC/DC (compatible with automotive 12V/24V systems) |
| Current Rating (Resistive Load) | DC 13-12V/24V 5A; AC 15-110V/250V 5A |
| Current Rating (Inductive Load) | DC 13-12V/24V 125A; AC 15-110V/250V 1.25A (handles high inrush currents in lift motors) |
| Mechanical Life | Up to 1,000,000 cycles (DC 13-12V 0.5A) — ideal for high-frequency use in lift systems |
| Operating Temperature | -30°C to +85°C (performs in extreme hot/cold automotive environments) |
| Switch Combinations | 1NO1NC/2NO2NC (one normally open/closed, two normally open/closed) — flexible for circuit control |
Why It’s Perfect for Automotive Start & Lift Systems
- Automotive Start Systems: The large silver contacts handle the high inrush current of engine starters, while IP67 waterproofing protects against under-hood moisture and debris.
- Lift Systems: The maintained/momentary options align with lift “hold” (maintained) and “pulse” (momentary) control needs; the durable metal construction withstands constant mechanical stress.
- Pre-Wired Convenience: Our pre-wired configurations reduce on-site installation time for your engineering team, cutting labor costs and minimizing setup errors.
Customization Options for Your Business
We offer B2B buyers tailored solutions to match your specific system requirements:
- IP rating upgrade (from IP67 to IP68).
- Custom LED colors (red, yellow, green, or multi-color).
- Custom switch combinations (1NO1NC/2NO2NC).
- Branding/labeling (custom logos on the button face).
Whether you’re sourcing components for automotive fleets or industrial lift equipment, the 22A Series Waterproof Metal Push Button Switch delivers the durability and performance your business demands.
