Laser Machine Membrane Keypad

Laser machine membrane switch with screen printing technology the relevant graphics, Windows, identification and control circuit printing on PET substrate, and then through the double-sided adhesive glue the layers together again, with high viscosity on the back of 3 m glue, waterproof and oil, in the assembly in the laser machine is more stable, at the same time the design button USES embossing process, and internally embedded metal shrapnel, has a more intuitive by pressure and strong sense of touch. The connection aspect USES the female end connector, more convenient switch and the following control board connection.
