According to the model number of the combination switch can check more technical parameters, the main technical parameters characterizing the performance of the combination switch are

(1) Rated voltage

The rated voltage is the voltage that the switch can withstand in long-term operation under the specified conditions.

(2) Rated current

The rated current is the maximum working current that the switch is allowed to pass for a long period of time in the closed position under the specified conditions.

3) On-off capability

On-off capability refers to the maximum current value that can be reliably switched on and off at the rated voltage under the specified conditions.

4）Mechanical life

Refers to the need for repair or replacement of mechanical parts before the need to withstand the number of unloaded operations

(5) electrical life

Refers to the specified normal operating conditions, without the need for repair or replacement of parts, with load operation times.
