LA38 22mm Push Button Momentary Switch Heavy Duty RED

The LA38 is a heavy-duty momentary push button built to the standard 22mm industrial panel-mount size, the same cutout diameter used across most industrial control panels, machine enclosures, and DIY control boxes – meaning it drops into standard 22mm mounting holes without needing a custom cutout. As a momentary switch, it only closes its contact while actually being pressed, springing back to rest the instant it’s released, making it suited to start/stop and trigger-style actions rather than a latching ON/OFF state.

Its heavy-duty construction is built for frequent actuation and panel-mount durability well beyond what a small PCB tactile button is rated for, making it a common choice for control panels, machine start/stop buttons, and enclosure-mounted manual triggers – red is conventionally used for stop, emergency, or “off”-style actions on a panel.
