Electrical Contacts Overview
- Minimum of self-inductance
- Very low DC resistance
- Minimal insertion loss
- Spring lifetime (100 cycles - infinity)
- Good electrical contact between mating parts with moderate forces
- Seamless and non-porous - no permeability of dust, dirt, or moisture
- Available in micro sizes
- Reduce tolerance build-up
- Maximum current rating (4 amps)
- Operating temperature range without spring rate loss (-423 °F to 260 °F)
Life expectancy ranges from 100 cycles to infinite. For greater life cycles, the maximum compression is reduced by 20% for 100,000 cycles and by 30% for infinite life. Our contacts can be used safely up to 260 degrees F while maintaining their full spring qualities and have no low-temperature limit.
These products are rated for a maximum of 4 amps.

Electrical Contact Applications
MW offers gold-plated electrical contacts using bellows technology. Our bellows electrical contacts are preferable to traditional contacts since they reduce signal loss and increase the signal's speed. Rather than travel along the path of a spring, the signal travels the walls of the bellows to get the maximum signal in the least amount of time.
These electrical contacts are available in both male and female configurations for applications that require pairing connections. These mated connections are self-aligning, which simplifies the assembly process. The self-aligning contacts minimize shock and vibration in dynamic applications and help overcome tolerance build-up or stacking when pairing circuit boards together. This also reduces the overall scrap cost of assembly components. Other applications may have the contact make an electrical connection with a pin or feedthrough hole.
We manufacture bellows electrical contacts with outside diameters ranging from 0.037″ to 0.125″. To enhance their conductivity, the contact springs are made from electrodeposited nickel and gold-plated to ASTM B488. These materials also offer meager DC resistance with a minimum insertion loss while operating up to 4 amps. All our bellows electrical contacts are designed to provide lifetime spring and force repeatability.
Our railway electrical contacts are used in electrical transit systems and are designed to be customizable to exact required working conditions. When traditional production methods are used to create electrical transit contacts, wicking and sticking can happen, which causes electrical failures resulting in costly warranty problems.
Our specialized engineering support team can evaluate systems failures and provide support and design assistance to resolve costly issues with existing components by creating alternative products specially designed for your application environment. In this case, this means creating movable electrical contacts produced using intensive internal cycle and pull testing to ensure zero defects which in turn substantially reduced failure rates and warranty concerns.
