DS-428 Yellow Push Button Switch with Lock — 12mm Self-Locking ON-OFF Switch

Looking for a reliable yellow push button switch with a locking mechanism? The DS-428 is your go-to component for projects that demand a switch that stays in position once pressed.

What Is the DS-428 Yellow Push Button Switch?

The DS-428 is a compact, round 12mm push button switch available in a self-locking (latching) version. Unlike momentary switches that reset on release, this switch locks into the ON or OFF position when pressed — making it ideal for power control, indicator panels, and automation systems.

The yellow color makes it highly visible on control boards, dashboards, and industrial enclosures, often used as a caution or function indicator button.
