The 3-1437569-6 is an instrument-grade, non-oiltight illuminated pushbutton switch designed for 16mm panel mounting. It provides momentary action with three normally open and three normally closed (3 N.O. & N.C.) snap-acting double break contacts. The contacts are gold-plated over silver clad, making them suitable for both power switching up to 5A at 250 VAC and logic-level circuits. This switch features a life expectancy of 100,000 operations and is relampable from the front panel using a T1-3/4 midget flange base lamp. Its IP40 rating and wide operating temperature range make it a reliable choice for various industrial control and instrumentation applications.
