SMK Develops a Push Switch with an Improved Click Ratio and Sharper “Snap” Feeling

 SMK Corporation has expanded the existing product lineup of push switches by developing its "HCF (High Click Feeling) Series" featuring an improved click ratio of minimum 35%.
 The HCF series switch was developed to operate automotive equipment requiring a high force typically required in keyless entry systems and car audio devices. The small switch has a crisper “snap” feel while retaining the high operating force of 4.8N in line with the current switches in the SMK lineup.
 The latest push switch has the same external dimensions as the current products in this lineup and therefore allows for a drop-in solution without having to change the board pattern. Another advantage of this switch design is it allows for applications where board space is limited and a high force is required.
