Designers looking for a robust waterproof limit switch, will almost certainly run across our switches at some point. It’s that “all roads lead to Rome” thing. Sometimes however, its not just the stainless steel, high electromechanical endurance aspect of our switches that wins the day with

Sometimes, the best engineering advances arise out of failure. To quote Thomas Edison “I have not failed. I’ve just found 10,000 ways that don’t work!” Indeed as one looks at the development history of CPI’s patented J4 ball switch, its current category leading performance did not

Sometimes in engineering design, you just get it right. The right combination of materials, simplicity and elegance. Just the right amount of cleverness. Sometimes it even looks pretty. Sure as time goes on you make tweaks here and there, but if your basic design is

Engineers and system designers looking for reliable switch products often face a quandary. Selection of switches with their inherent mechanical limitations must be pondered carefully or they risk being the proverbial “weakest link” in an otherwise robust control or safety system design. When switches are directly

Behold the simple yet much misunderstood start switch, deployed ubiquitously throughout every corner of the world, almost everywhere there is an electronic motor or actuator of some type. Simple matter of closing a couple contacts you say? Well we beg to differ because in the
