Schneider Electric Harmony Series Push Button, Panel Mount, 22mm Cutout, SPST, IP66, IP67, IP69(IP69K)

This round pushbutton from Schneider Electric is marked with a down arrow, making it ideal for controlling machine movement. For ease of operation, you can use it with other pushbuttons to control forward, backward, horizontal and vertical processes. It's a momentary pushbutton, so it's only actuated when actively pressed, making it a good choice for temporary processes. The unit calls for a standard 22mm cutout for straightforward mounting on a control panel. Screw-clamp connectors ensure a secure connection that won't come loose easily, even in situations where heavy vibration is likely.
