Glossary

• Oil-tight: A generic term for a panel seal (see) commonly used

in industrial settings. Defined by NEMA (see) and IP (see)

standards.

• Operating Force: See Actuation Force.

• Operating Temperature: The range of temperature within

which the device may be used. Unit of Measure: Degrees

celsius or fahrenheit (C or F).

• Operator: A panel mounted mechanical device (pushbutton,

selector, keylock, etc.) without contacts to which one or more

contact blocks (see) may be added to make a complete switch.

• Overtravel: The distance the actuator may move between initial

contact position and the extreme mechanical position of the

actuator without damage to the switch. See travel. Pretravel.

Unit of Measure: Inch. Degree.

• Panel Seal: A panel seal provides a defined level of protection

against penetration of liquids through which the switch and

switch-to-panel interface to the rear of a panel. Unit of

Measure: Inches/ft. of water.

• Pole: The number of separate circuits that can be active through a

switch at any one time. A single pole switch allows one closed

circuit at a time. A double pole switch allows two closed

circuits, etc.

• Power Factor (PF): A measure of the inductive or capacitive

character of an electrical load. Unit of Measure: 0 to 1 (e.g.

0.75)

• Process Seal: A seal that prevents damage to or contamination of

the switch during the specified mechanical process. See wave

solderable. Surface Moutable.

• Push-On/Push-Off: See Push-Push.

• Push-Push (Alternative Action, Push-On/Push-Off): A

pushbutton switch style in which the electrical state of the

switch is maintained between actuations of the plunger.

• Quick-Connect Terminals: Flat tab or blade style terminals

designed to accept push-on female wire connectors (instead of

soldering). The most popular sizes are: 0.250”, 0.110” wide.

• Resistive load: A load in which the current and voltage are in

phase. See Capacitive Load, Inductive Load, Power Factor,

Inrush.

• Shorting Contact: See Make-Before-Break.

• Single Break Contacts: A contact mechanism using one set of

contacts to make or break a given circuit. Typical of electronic

or low power switches. See Double-Break Contacts.

• Splashproof: See panel Seal.

• Spring Return: See Momentary.

• Storage Temperature: The range of temperature within which

the device may be stored. Typically this is a wider range than

operating temperature. Unit of Measure: Degrees celsius or

fahrenheit (C or F).

• Surface Mount Devices: Components that are compatible with

surface mount PC board technology. Holes are not used for

component mounting. Component leads are soldered to pads on

the surface of the PC boards. For switches typically defined by

surface mount terminations (e.g., J-bend, L-bend, butt, etc.) and

compatibility with surface mount soldering (e.g., vapor phase

reflow, infrared, etc.) and cleaning processes.

• Tactile Feel (Feedback): A mechanical signal (typically a

“snap” or “click”) that indicates contact closure to the operator.

• Terminal: The metal portion of the switch, exterior to the body,

that is used to connect the switch to an electrical circuit.

Examples: PC, wire lug, Turrett, quick-connect, wire-wrap, etc.

• Throws: Number of circuits that can be controlled by any one

pole of a switch. Example: In a single pole — double throw

(SPDT) switch, only one circuit may be completed at a time.

However, there are two possible circuits (throws) that can be

made.

• Travel: The total distance the actuator moves to change electrical

position. See Pretravel. Overtravel. Unit of Measure: Inches,

degrees.

• Washable: Applied to PC board mounted devices indicating

compatibility with cleaning processes used after soldering. No

degredation of electrical or mechanical parameters occurs.

• Wave Solderable: Indicates the device is suitable for the wave

soldering and cleaning processes as supplied. See Process Seal.

• Wiping Contact: A contact mechanism in which the movable

contact with the fixed contact with a wiping motion. Typical to

slide and rotary switches.
