Panasonic ESP User Manual
Tact il e Sheet
Typ e:
ESP
The part of switch is designed for thin and small
electronic devices such as mobile phones.
Creates thin push switches when combined with fi xed
contacts on a PWB.
■ Features
● Resistant to environmental degradation:
1) Diaphragms with a center hole ensure contact stability.
2) Silver-plated diaphragms achieve high contact stability.
● Metal diaphragm creates a thin profi le and lightweight.
● Sharp click-key operational feel.
● SMD available by using roll packaging (refer to the
diagram below).
