The heavyduty metal keys, front plate, and mechanism are designed for outdoor anti-vandal service in telephones, ATMs, vending machines, and similar applications. Shouldered pushbuttons cannot be removed. Deeply engraved legends resist defacing by coins, keys, or other tools. Standard 12-key telephone and special 13 to 20-key layouts feature matrix circuits. Reliable keypad performance is assured with more than 1-million operations.
