Abstract
A component having an externally engaged actuating member which effects an internal change at what is required to be a closely repeatable position in the movement of the member, e.g. a micro-switch actuated by a push button, is calibrated by progressively moving the actuating member while sensing for the internal change then, when the change occurs, clamping the actuating member (e.g. the push button) and cutting it to length.
Claims7
An automatic process for calibrating components of a kind including an actuating member on the component movable from a first position to a second position causing a change of state within said component, said actuating member having a greater extent than required to cause said change of state, the purpose of the calibration being to ensure that the change of state occurs at a predetermined position of an externally engageable surface of said actuating member in relation to the remainder of the component, said process comprising applying a force to said actuating member progressively to cause said member to move from said first position towards said second position while monitoring for the internal change of state, then, when said change of state occurs, holding said member in the position it has then reached and, while it is held, removing material from said member to form said externally engageable surface occupying said predetermined position.
