Door clutch/interlock mechanism in switches have IP66/67 protection to suit operation in more aggressive environments rather than the IP 65 protection of the old design.
U k solenoid, the leading low voltage switch and control gear supplier of Kraus and Naimer Blue Line products have introduced a new design for the door clutch/interlock mechanism of Size 1 to 3 switches to provide improved IP protection. As a result of some innovative design changes the door clutch/interlock mechanism now offers IP66/67 protection rather than the IP 65 protection of the old design. The size 0 version remains IP 65 although it is planned that a version offering improved protection will be available soon.

Sales manager Norman Allan comments: 'The prevention of water or particle ingress is of very high importance in a number of aggressive environments so this development will enable design engineers to specify our products secure in the knowledge that they will provide a very high level of protection.'
