Switches of A and A30 Series do not have a legend plate and are only fitted with a knob. These switches are mainly dedicated for special purpose devices (e.g welding machines), where the marking of each switching position is printed (e.g. in silk screen printing process) on the front panel to which the switch is fitted.
