Finish
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.
For high mechanical strength and high electrical insulation.
The small rear end of the switch allows space saving behind the panel.
Matt black finish on body, bushing, lever and hardware.
Panel sealed to IP 67, these switches are frontal sealed by two O-rings and
have full rear end sealing.
A comprehensive range of protection boots (both full and half length), locking
levers and security caps are available.
