Data Sheet

DG sub-subminiature switch
Extremely small dimensions – only 12.8 × 5.8 × 6.5 mm.
Breaking capacity ranges from small switching
currents and voltages to low-voltage applications
up to 3 A 125 V AC.
∙ Available with or without auxiliary actuator
∙ Use on circuit boards with connections to the left
or right and standing
∙ High mechanical operating life,
depending on model > 1,000.000 operations
