Abstract
A method of monitoring a contact force between electrical contacts in a mechanical contactor. The method includes receiving, from a force sensor, a signal including information about a base force sensed by the force sensor between a stationary core and a base; determining a magnitude of the contact force based on the received information; and outputting information based on the determined magnitude to an operator.
