Operating Notice:

      There is a protector of over-current between electrical  control system and solenoid, in order to prevent the solenoid and the electrical component from burring in improper conditions.

The handle operating button is fit for adjustment,service and sometime in emergency.

 

Explanation of Sample:

If client have special requirements, we can adjust the connect dimension, power connect method and the extended length of push pin as demanding.
