The ComEx Ex i illuminated button indicates command modes by means of a light signal lighting up or going out. It is suitable for use in almost all hazardous (potentially explosive) areas in which a visual indication of the machine’s functional status is required. The illuminated buttons are designed to conform to the requirements of the “e increased safety”, “d flameproof enclosure”, and “i intrinsic safety types of protection”. They may be activated by intrinsically safe circuits. The illuminated buttons can be combined with various lamp module actuators. Each illuminated button actuator is fitted into a mounting hole in a control console or a control panel. The respective illuminated button is intended for fitting onto a mounting rail. Conductors are connected using terminals with increased safety on the back of the module. The lamp module actuator can be fitted easily without tools, which ensures conformance to the high IP degree of protection.
