InteruttoriThe pressing of a button, the closing of a switch, and the ignition of an engine; these are some of the many control actions that can induce a double stress to the component being operated on: the first of an electrical nature, and the second of mechanical origins.

The mechanical wear is quite evident and it is controlled by the designer; choosing the lubricant that is best suited to the operating conditions can ensure prolonged functionality.

Electric Arc


Less obvious and especially difficult to quantify is the electrical stress that a command undergoes during the interruption or activation of the current flow. The sudden approach of two conductive surfaces inside an electrical switch is a crucial time, and even a proper design cannot prevent the formation of an electric arc: high temperatures, which are incompatible with any material, last for fractions of a second and produce micro-damage to the conductive surfaces responsible for the passage of current.

With one action after another, the effects of the electric arc produce an inevitable increase in contact resistance within the switch, with a possible appearance of defects and irregular operations for transmissions of low intensity signals.

Macon Research has always been active in the development of lubricant solutions for electrical switches, the choice of which depends on the design and electrical conditions: front, swinging, sliding contact switches, potentiometers, and connectors.
