Release Force:

The force that is applied to the button or toggle when the switch contacts return to their unoperated position.

Open Frame:

Typical to slide switches; open frame construction allows for automatic solder process and post solder cleaning. Contrast with “washable”.

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.
