Exposure hand switch equipped with RJ12 crystal head

Recently, a customer in Taiwan asked about the exposure hand switch produced by Newheek and wanted a 4-pin, 3-meter-long product with a crystal plug. Send the information of our company’s exposure hand switch to the customer. After reading the information, the customer said that they needed 5 L01 4C3M X-ray exposure hand switches with crystal heads. The customer sent them to the account in US dollars, and then gave the PI for making the exposure hand switches to the customer. Exposure hand switch * 1 USD, shipping fee is 3 * USD. It is necessary to connect the exposure hand switch to the RJ12 crystal head. The customer has sent me the wiring diagram of the RJ12 crystal head.
Regarding the wiring problem of the RJ12 crystal plug, the color of the exposed hand brake wire is different from theirs. Tell us that all L01 exposure hand switches are black and white in the first gear, and red and green in the second gear. The color may be different from the color they sent.
