Data Sheet

D4 miniature switch
Versatile miniature snap action microswitch. A wide
variety of auxiliary actuators and terminal options are avail-
able as standard and the switch fulfi ls the requirements of
IEC603351: GWFI at 850°C, GWIT at 775°C and GWT750°C.
∙ High proof tracking index PTI 600
∙ High level of repeat accuracy
∙ High contact stability through application-specifi c contact
materials up to a switching current of 0.1 to 21A at 250V AC
∙ Ambient temperature – 40 to + 150°C
∙ Approved according to IEC 61058-1 / UL 61058-1
