Originally designed for demanding military vehicle applications, the J4 Series switches replace standard ball switches in applications such as neutral safety switch, where harsh envirnonments caused high failure rates.  At the heart of the J4 is a patented ball carrier design which prevents contaminates such as mud, dirt, ice, sand, dust, etc. from jamming the ball.

These switches are also ideal for heavy industrial equipment applications that are subject to the same conditions. The switches are completely submersible and are unaffected by water, salt spray, humidity, dirt, dust, sand, icing, oil, shock and vibration.
