The ComEx switching module can be used in almost all potentially explosive areas where machine functions need to be triggered by a button or a switch. ComEx switching modules are flexible in use and offer a range of actuator elements. All contacts of the switching module are selfcleaning, and NC contacts have positive opening. The conductor is connected using terminals with increased safety on the back of the module. The simple installation of the actuator elements without tools guarantees the high IP protection type.
