12000X778 series

12000X778

New product

This range of professional toggle switches is suitable for use in military and other high specification environments. CECC and MIL approved, the 12000X778 toggle switch has a double shell case construction and pinned lever for extra mechanical strength and robust seal up to IP67. Available with solid rivet contact: gold plated silver/nickel alloy.  Comprehensive range of sealing boots and security caps available.

Main features

  • Approvals: CECC 96201-005 CECC 96201-008 MIL-DTL-3950 MIL-DTL-83731
  • Contacts: Highly reliable contacts suitable for low level applications (10mA 50mV - 10μA 5VDC min.) or power applications (2A 250VAC - 4A 125VAC - 4A 30VDC max.)
  • Pinned lever: The base of the switch lever is pinned to the bushing, thus earthing the lever to the bushing. This also provides strain relief to protect the switch if accidentally knocked.
  • Double shell case: For high mechanical strength and high electrical insulation.
  • Compact size: The small rear end of the switch allows space saving behind the panel.
  • Finish: Matt black finish on body, bushing, lever and hardware.
  • Sealing: Panel sealed up to IP67, these switches are frontal sealed by two O-rings and have full rear end sealing.
  • Accessories: A comprehensive range of sealing boots (both full and half-length), locking levers and security caps are available.
