Abstract
Keypad devices have become commonplace in everyday life. They are part of our everyday life, in the form of pocket calculators, telephones, remote control devices, and cellular phones. Cleaning these keypad devices is problematic, since they have a large number of actuatable keys, due to the functions to be performed. As a mechanical interface in the keypad device, each key is a critical weak point in terms of maintaining a tight seal. An easy-to-clean keypad device, in particular an emergency call device, has a main body, an electronic assembly—which includes circuit elements and is installed in main body—a closing shell and keys, which are installed in closing shell and are designed to mechanically actuate the circuit elements. Closing shell with installed keys is a first preinstalled assembly, and main body with installed electronic assembly is a second preinstalled assembly. The first and second preinstalled assemblies are interconnected such that they may be separated.
