10-Serie 12000X778-A-R1 11-Serie 12000X778-A 30/10/14 15:13 Page72 12000X778 series High performance toggle switches - threaded bushing 11,9 (15/32) Distinctive features UG1410A Approvals CECC 96201-005 A CECC 96201-008 MIL Standards MIL-DTL-3950 and MIL-DTL-83731 This range of professional toggle switches is suitable for use in military and other high specification environments. Contacts Highly reliable contacts suitable for low level applications or power applications 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 Black finish on body, bushing, lever and hardware. Sealing Panel sealed to IP 67, these switches are frontal sealed by two O-rings and have full rear end sealing. Accessories A comprehensive range of protection boots (both full and half length), locking levers and security caps are available.
