Momentary Switches for Extreme Duty – Reducing Failure Rates.

Momentary Switch Design Parameters

Extreme duty applications that require a momentary switch with potential for extreme temperature ranges or constant operation require more than just switch waterproofing. For more than 40 years CPI’s has made precisely engineered waterproof switches for the Military and Heavy Equipment industries that achieve the most stringent requirements for operation.  By expertly trading off the many conflicting design requirements necessary to achieve an overall goal for MTBF, cost, and electrical parameters, CPI has been able to meet almost any momentary switch operating specification.  

Not to mention that our switches are truly “waterproof”, not water-resistant.  You can’t drown our stuff…(-:

Some of the design considerations for our switches include the following:

CPI Waterproof Pendant Switches,

1.     Operating Temperature Range. CPI has engineered our Pendant switches to avoid contact “freezing” at operating temperatures down to -65F.  (mil-spec)

2.     Contact travel and pre-travel – These critical parameters affect MTBF directly and must be adjusted to achieve the specified cycle lifetime

3.     Mechanical Endurance – CPI has achieved MTBF of over 1 million cycles rated for high dynamic temperature environments, with careful design of mechanical switch parameters, and new manufacturing techniques for sealing.

4.     Actuator Style – The actuator used for our momentary switch configurations can be specified: either plunger, lever, roller ball, or hand actuated pendant style switches. All with unique engineering challenges to achieve an overall requirement.

5.     Circuit type – Normally Open/Closed and current requirements can be specified for any switch we build, including the challenge of designing for high startup loads.

6.     Mounting & Packaging. CPI provides a wide variety of packaging options with any switch. Each present unique challenges for design and operation that CPI’s experienced engineering can solve.
