Installation of hand switch connector

What are the problems that need to be confirmed for the connection to install the hand switch
Many hand switchs purchased from Newheek require them to install connectors, and crystal connectors are more commonly used. When installing the crystal, in order to be able to match the X-ray machine, we will confirm to the customer the model of the crystal connector. Because there are many types of crystal connectors, engineers must know the exact model to install the correct one. Then it is necessary to confirm the arrangement order of the core wires, and different core wires control different gears of the hand switch. In order to avoid wrong connection, it is best for customers to provide accurate wiring diagrams.
