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 operated by humans, the equation becomes even more complex. Tactile factors come into play, as well as consideration of the ergonomics of mounting and positioning these switches in vehicles or machinery that may be exposed to severe weather, temperature, vibration or all of the above.
Push Button Switch Actuation
In addition of offering some of the industry’s most hardened waterproof switch designs, CPI switches come in a number of form factors, suitable for almost any deployment
Hand Actuated – CPI Pendant Switches can come in momentary or maintained closure options and are completely submersible. Extended temperature operation is achieved through either Neoprene or Santoprene sealing with leads completely sealed and extending from the switch body in any length required. Both standard and “light touch” actuation versions available.
Rolling Ball Switches – Our all stainless steel, rolling ball switch option (J4 series) is ideal for applications requiring a low profile, non-linear activation in a harsh operational environment. The J4 is a patented ball carrier design which prevents contaminates such as mud, dirt, ice, sand, dust, etc. from jamming the ball.
Applications include transfer case gear position sensing, neutral safety detection, Hydraulic valve position indication, PTO switching, door switch, backup safety alarm, and interlock switch detection.
Plunger Switches – Based on the J4 seal design, our plunger switch allows designers to be sure that waterproof performance can be maintained in extreme environments with electro-mechanical endurance up to 5 million cycles. Plunger size and activation force can be custom specified, and our patented exclusion seal insures the contacts against sand, dust, dirt, mud, rain and pressure washer abuse.
Limit Switches – By mounting our pendant switches in a series of enclosures, CPi can offer operational limit switch variations suitable for a wide variety of industrial applications.
| · Roller Limit Switch | · Roller Lever Flush Mount |
| · Simulated Roller Limit Switch | · Roller Lever Angle Mount |
| · Straight Lever | · Profiled Lever, Flush Mount |
| · Simulated Lever | · Dual Switch, Simulated Roller |
And many more mounting variations are customizable.

There are a number of safety systems present in Forklifts and Telehandlers for which CPI waterproof switch products often get selected. Since these specialized vehicles often operate outdoors in less than ideal conditions on construction sites, a tough and durable switch is essential to both equipment uptime, and job safety.
For this application our J4001 ball switch is often used owing to its highly robust all stainless steel design, and its qualification for extreme electromechanical endurance. 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. Furthermore the switches are completely submersible and are unaffected by water, salt spray, humidity, dirt, dust, sand, icing, oil, shock and vibration.
site, you’ve for sure heard that loud annoying beeping sound whenever a lift moves backwards. That doesn’t happen without the engagement of a switch like our E1078
