• Lever limit switches used for heavy-duty eot cranes, wagon shunting devices, etc, to prevent over travelling or over traversing on power and control circuit up to 500 v ac 50 cycles/second and 40 a current rating. This crane control-make lever limit switch normally remains closed and cuts off power to stop the motor of the particular motion, which operates when its lever reaches its pre-determined position and is moved over a projecting member fixed on the girder. The switch contacts are automatically reset when the lever returns to zero position due to spring action. It is made in ip-41 as well as in ip-54 enclosures. The contacts have a maximum continuous current capacity of 40 a ac and are made of high-grade silver cadmium oxide alloy. When used for series operation up to 40 a maximum, the contacts are suitable for 720 operations per hour and in case of shunt operation for control circuit, the contacts are suitable for 1200 operations per hour. The same contacts can be used in series as well as in shunt configurations. The material is non-tracking and is capable of withstanding heavy arcing. .
