1) the rated voltage of rated voltage is refers to under prescribed conditions,switch in the long-term work under high voltage.

2) electric motor 12v 500w rated current rated current is refers to under generator stator prescribed conditions,the switch in the closing position allowed by the maximum working current for a long time.

3) on and off On-off ability under prescribed conditions,can reliably connected under rated voltage and breaking the maximum current value.

4) mechanical life Refers to the need to repair or replacement under the mechanical parts of no load operation.

5) electric life means under the mini electric motor condition of the normal work of the regulations,does not require repair or replacement parts,the number of times the load operation.

Combination switch used for isolating switch,the rated current shall be the is less than the sum of the load current in isolating circuit; Used to wholesalemotor.blogspot.com control the motor,the rated current generally take 1.5 ~ 2.5 times rated current of the motor. Shall be determined according to actual needs in the electrical control circuit,the connection mode of automobile combination switch,correct selection to meet the requirements of wiring combination switch specification.
