The 1019.5101 is a single-pole snap-action switch (Schnappschalter) designed for AC circuits. It carries electrical ratings of 5A at 125-250V AC and 6(2)A at 250V~ with a T85 temperature rating. The switch has a required operating force between 1.5 N and 3.0 N, a differential travel of less than 1.2 mm, and a switching point at 2.4 ± 0.6 mm. Its normally open configuration makes it suitable for applications requiring a momentary circuit connection when the actuator is pressed.
