Choosing the right size metal push button switch can be confusing. This guide covers 8mm, 10mm, 12mm, 16mm, and 19mm models, comparing their applications, features, voltage, waterproof rating, and best uses to help you pick perfectly.
Why Choose Metal Push Button Switches?
Metal push button switches are widely used in industrial control, automotive, DIY electronics, PC power, machinery, and outdoor equipment because they are:
- Waterproof & dustproof
- Durable metal housing
- Support momentary (self-resetting) & latching (self-locking)
- Built-in LED indicator for clear status
- Wide voltage: 3V–24V DC / 110–220V AC
- Easy wiring with plug‑in or pre-wired cables
