STANDARD SW195
NC - DP - ST
The SW195 series of contactors has been designed for direct current loads, particularly motors as used on electric vehicles such as industrial trucks and airport tractors.
The SW195 have double breaking main contacts with silver alloy contact tips, which are weld resistant, hard wearing and have excellent conductivity. Mounting is by means of 5 mm tapped holes in the switch frame together with a range of mounting brackets.
