SMK Develops Rubber Push Switch with Improvements to Mounting Stability

 Praised throughout the industry for their excellent operability, SMK Corporation has improved on its "JPM Series" rubber push switch mounting stability.
 The mounting stability has been improved by adding SMK’s innovative multiple step structure located at the housing case bottom, which minimizes the following:
 1. Instability due to uneven PCB resists and land pattern printing.
 2. Soldering flux during the reflow soldering process.
 The key stem and case mounting area ensures excellent usability by improvements to SMK's unique internal structure. The switch does not have a “designated push” area and can be operated along the edges as well as the center of the key for better overall performance. (Patent No. 4414412)
 The JPM series switch consists of two load variations (short: 1.3mm, standard: 1.5mm) to satisfy all mechanical designs.
