Operate Force:

The amount of force it takes to make the toggle or button operate the switch, measured immediately before the switch operates.

Resistance (Insulation):

Resistance of electrical isolator between two electrodes, defined by Ohms Law as result of division of the applied voltage and measured current. Not to be confused with dielectric strength.

Operating Point:

The position of the button or toggle of a switch when the switch operates. The operating point is usually measured from the top of the button to the center of the mounting holes in basic switches or from the free position of the button in pushbutton switches.
