DESCRIPTION
The TP 1251 series of miniature, PCB mounted, pushbutton switches is designed for applications that demand a
minimal overall height and are particularly suitable for illuminated membrane switch panels. The switches are fully
backlit and are available in red, yellow and green and exhibit a high degree of brilliance due to an innovative filter
and reflector construction. A simplified operating mechanism and low current requirement ensure high reliability in
use.
