Years of in-depth experience of handling challenging requirements has enabled us to develop some revolutionary products. These products use Unique Capacitive Mechanical Sensing Technology for making contacts which are patented by SBL.

Single Capacitive Switch with two Progressive Functions
The CAPMECHTM series switches are not the commonly created ordinary switches albeit having looks similar to a mechanical push button. With features of the backlight and progressive functions, these switches are essentially capacitive switches. These switches use Unique Capacitive Mechanical Sensing Technology for making contacts which are patented by SBL. With this unique feature, it allows the user two separate progressive contacts in a single contact. It is primarily used in the medical industry, automobile, consumer electronics, test and measuring equipment etc.
