The miniature tilt switch type RBS020402 has been modified to offer improved contact resistance and increased switching life. Changes to the switch's internal design, enabling the contact to move smoothly, and improved gold plating on the switch housing and ball contact have improved the reliability of switch operations. The switch is designed to fit into a recess punched in the printed circuit board. This gives the switch less than 3mm height profile when located in the recess. The miniature tilt switch is easy to handle and has an overall size of 4mm diameter by 8.6mm long with two 1.2mm pin electrodes.
