D4 series switches with U.S. mounting
holes have optional VDE approval. Contact
factory for part number. Switches with
straight terminals may require insulated
connectors for international approval.
Reinforced mounting holes
totally contained in case to
provide maximum distance
to mounting hardware.
Choice of U.S. (#4 screw)
or metric (3mm screw)
Offset terminals
maintain adequate
spacing when quick
connects are used.
Single or double throw,
either normally open or
normally closed
