Customer consultation exposure hand switch use

Recently, we received the customer’s inquiry about the exposure hand switch. First, we added the customer’s contact information, and then sent our exposure hand switch product information to the customer. We asked the customer what kind of machine they would like to use with the hand switch. The customer said that they would use it to match the portable X-ray machine. After confirming the customer’s contact information and receiving address, we made a quotation and sent it to the customer.
Customers asked what advantages our exposure hand switch products have over other products? Our product is equipped with a two-stage grading switch, which can be opened by pressing the button and broken when released.
