Terminal:

The metal portion of a switch, exterior to the body, that is used to connect the switch to an electrical circuit.

Voltage Drop:

Change in voltage that results from a current passing through a device. For switches Voltage drop is typically referred as Contact drop DV.

Example:

PC, wire lug, quick-connect, wirewrap, etc. Please refer to the ITW Switches Characteristics/Circuits for more detail.

Washable:

Applied to PC board mounted devices indicating compatibility with cleaning processes used after soldering. No degradation of electrical or mechanical parameters occurs. A switch is sealed to keep contaminants out of the contact area.

Throw:

Denotes the number of different circuits that each individual pole can control.
