The uploaded image shows a 12 mm threaded metal push-button switch, supplied with a hexagonal mounting nut and sealing O-ring. This style is commonly used as a compact panel-mount industrial push button. The exact electrical rating depends on the particular contact configuration; similar 12 mm versions are available as momentary 1NO and latching types.

Electrical Specifications
For a typical industrial 12 mm 1NO metal switch:
Parameter Typical Specification
Contact Type 1NO
Rated Voltage Up to 250 VAC*
Rated Current Up to 5 A*
Contact Resistance ≤50 mΩ
Insulation Resistance ≥100 MΩ
Dielectric Strength Up to 2500 VAC / 1 min
Electrical Life Up to 50, 000 operations
Mechanical Life Up to 100, 000 operations
A manufacturer specification for a 12 mm metal 1NO version lists 5 A / 250 V, ≤50 mΩ contact resistance, ≥100 MΩ insulation resistance and 50, 000 electrical operations.
Important: Do not assume every 12 mm metal switch has a 5 A/250 VAC rating. Some compact versions are only rated around 2 A/36 VDC, so the rating printed on the actual product/datasheet should be used for mains applications.
