It maybe necessary to allow a responsible person to switch ON a machine with a guard open, for setting-up and maintenance. Unimax strongly recommends the installation of a special high security keyswitch such as the seven-tumbler GW14 series.
The GW Series can be fitted with the same switching options as the standard GW and SAF ranges.
GW14 Switches must be sited so that the key shank projecting from the lock prevents the closing of the guard, as a reminder to remove the key after use.
Maintence keys are available for all 3 types of locks see below for override key for each system.
