12000X778 series
High performance toggle switches - threaded bushing Ø 11,9 (15/32)
Distinctive features
A
❑❑ Approval and lists
CECC 96201-005
CECC 96201-008
MUAHAG and QPL listed (Europe only)
French defence approved : DAT list No A5999 X001.
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 (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 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.
