Pushbutton Switches
This rugged sealed pushbutton switch uses a Hall-Effect sensor to achieve
extremely long life, up to 1,000,000 cycles momentary. This switch is suited for
harsh environments where long life and reliability are needed, and offers a wide
choice of mounting style, colours, terminations, lighting and momentary or
maintained switching.
