Plastic keypads -- EAO Switch Corp.

 The S Series Lite plastic keypads are suitable for indoor and outdoor use, such as in access-control systems, ticketing machines, telephone systems, payment terminals, and vending equipment. They are made from polycarbonate plastic and are as durable as their metal counterparts. A simulated scratch-resistant matte chrome finish protects to IP67 and is impact resistant to IK09 (10 joule). The devices can be front or rear mounted, and connect through an external pin-header connection.
Design options include laser etching which ensures markings remain sharp. Standard illumination is produced by either blue or yellow LEDs, and is visible through or around the legend. Two standard sizes are available: 12-key telephone or 16-key hexadecimal.
