SPST Push Button ON-OFF Switch (Panel Mount, Latching / Self-Locking)

Compact and durable Single Pole Single Throw (SPST) ON-OFF push button switch designed for power control in DIY electronics, robotics, custom instrument panels, and prototyping enclosures. Operating with a reliable latching (push-to-lock ON, push-again to unlock OFF) mechanism, it offers a distinct tactile click and solid electrical contact for seamless DC and low-voltage AC switching.

Equipped with a threaded bushing, mounting nut, and washer, this panel-mount switch easily installs into drilled enclosure panels, project boxes, or dashboards.
