High performance toggle switches - threaded bushing Ø 11,9 (15/32)
Distinctive features
K
Approvals
A
MIL
CECC 96201-005
CECC 96201-008
Standards MIL STD 3950 and MIL STD 83731
This range of professional toggle switches is suitable for use in military and
other high specification environments.
K
Contacts
Highly reliable contacts suitable for low level applications or power applications
K
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.
K
Double shell case
For high mechanical strength and high electrical insulation.
K
Compact size
The small rear end of the switch allows space saving behind the panel.
K
Finish
Black finish on body, bushing, lever and hardware.
K
Sealing
Panel sealed to IP 67, these switches are frontal sealed by two O-rings and
have full rear end sealing.
K
Accessories
A comprehensive range of protection boots (both full and half length), locking
levers and security caps are available.
