Panel Switches/ESP Tactile Sheet Type: ESP The part of switch is designed for thin and small electronic devices such as mobile phones. Creates thin push switches when combined with fixed 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 profile and lightweight. ● Sharp click-key operational feel. ● SMD available by using roll packaging (refer to the diagram below).
