Customer from Uzbekistan enquired about wireless hand switch

The Uzbek customer saw our wireless hand switch on Newheek’s and asked us if we had a wireless hand switch.We asked the customer what device he was using, and the customer sent us a photo of the device. It was a portable computer.We also confirmed with the customer whether the four-core cable is connected, and asked the customer to take a photo of the connection to us.After confirmation, we explained to the customer that the wired hand switch does not need to be connected to the power supply, but the wireless hand switch does, so we provided an additional battery box for the customer, and the customer needs to buy the battery by himself for use.The customer accepted our proposal.We have recommended bluetooth wireless hand switch and wireless hand switch to the customer. The customer thinks the wireless hand switch is more cost-effective, so he will reply to us after reporting to the leader.
