XB4-BA21 22mm Metal Push Button – Black Spring Return Momentary Switch 1NO

Need a solid, no-nonsense push button for a project or control panel?

This is an XB4-BA21 style momentary switch in a sleek black finish.

It's built with a metal body and a plastic contact mechanism, making it tough enough for both interior and even exterior use since it's dustproof and dust resistant.

This is a spring return (retractive) type, so it's a momentary action – it only makes contact while you're pressing it.

The contacts are configured as 1 normally open (1NO).

It works with both AC and DC current and handles basic on/off operations.

It comes as a single unit, weighs just under 3 ounces, and includes protection features like low voltage and black current protection.

Whether you're wiring up a custom rig or replacing a worn-out switch, this unbranded XB4-BA21 is a practical, affordable choice for any room or industrial setting.
