Parameter |
Description |
|
Actuation Window(in/out) |
The distance from the first switch contact change to the point where all contacts have transferred completely (no more bounce). |
|
Blackout |
The dead band that exists during contact set transition (differential measurement). |
|
Contact Resistance(max, min & avg) |
The resistance measured from the first contact change plus blackout to the point where bottomout occurs for inward motion, or to the point where button-free position occurs for outward motion. |
|
Free Position |
The location of the top of the switch button (actuator) with no force applied against it. The free position is measured with respect to a predetermined reference point. |
|
Movement Differential |
The difference in distance between the operating point and the reset point (differential measurement). |
|
Operating Force |
The maximum force measured during pretravel. |
|
Operating Point(or position) |
The point where all contacts have transferred at least once (ignores bounce). Measured with respect to a predetermined reference point. |
|
Overtravel |
The distance from the operating point to the point where bottomout occurs (differential measurement). |
|
Pretravel |
The distance measured from the button-free (rest) position to the operating point (differential measurement). |
|
Reset Force |
The minimum force measured from bottomout to the reset point. |
|
Reset Point |
The point where all contacts have transferred back, at least once, to their original (releasing position) positions (ignores bounce). Measured with respect to a predetermined reference point. |
|
Reset Travel |
The distance from the reset point to free position (differential measurement). |
|
Simultaneity> |
The distance from a reference contact set or first contact, to the actuation of another contact set. Measured when more than one contact set is being tested. |
