Die cast aluminum housing based limit switches have extensive applications in different industries for smooth running of industrial plants, burst protected machines and outdoor equipments. Their housing consists of two circuit dual cut off switch with automatic on/off function. To meet exact application requirements, limit switches are offered in different operating temperature ranges and various resistance capacity based options ( as for instance, low temperature resistance/weather protected/rust resistance etc). Designed as per IEC norms, housing of these switches is burst proof. Long life span is one of the key aspects of these switches.
