Glossary

• Actuation Force (Operating Force): The force required to

change the actuator of a switch from one position to the other.

Unit of Measure: Slides - lbs., oz. or grams. Toggles and

pushbuttons - oz. Rotary products-torque.

• Actuator: A movable part of a switch which causes a change in

the electrical configurations of the switch.

Example:

Toggle

Rocker

Slider

Plunger

Paddle

Shaft

• Alternate Action: See Push-Push.

• Angle of Throw: The angle or arc through which an actuator

passes during actuation. Typically used to refer to the

movement of toggle or rocker actuators. Unit of Measure:

Degree.

• Antistatic: An antistatic device will withstand a specified

potential without conducting between the actuator and any

conducting element, usually the terminals or bushing. Unit of

Measure: Typical value 15-20 kilovolts DC.

• Bifurcated Contact: A wiping movable contact consisting of

two spring fingers that grip fixed contacts. Typically found in

slide switches. Self-cleaning action. See Wiping Contact.

• Bobbin Contact: A movable contact shaped like a thread bobbin

that rolls along the stationary contacts. Found only in slide

switches.

• Bounce: See Contact Bounce.

• Break-Before-Make (Non-shorting, Break First): On

actuation, the movable contact breaks contact with one fixed

contact before making contact with another fixed contact.

Contrast with make-before-break. Typical of toggle and

pushbutton switches. (BBM)

• Break First: See Break-Before-Make.

• Butt Contact: A contact mechanism in which the movable

contact makes contact with the fixed (stationary) contact

without wiping motion between the surfaces. Typical of toggle

and pushbutton switches. See Wiping Contact.

• Capacitive Load: A load in which the initial current on making

(closing) of the contacts is higher than the steady state current

on breaking (opening) of the contacts, the current is less than

steady state. Current leads voltage in capacitive loads. See

Resistive Load, Inductive Load, Power Factor and Inrush.

• Carrying Current: The maximum current that can be passed

through the already closed contacts of a switch. Contrast with

“Contact Rating.”

• Contact (Contact Area): The metal surfaces that come into

physical contact to complete an electrical circuit. These

surfaces are found on moveable contacts (see) and terminals

(see).

• Contact Block: A switching element which is added singly or in

groups to an operator (see) to make a complete switch.

• Contact Bounce (Bounce): The time during switching in which

electrical instability caused by the rebound of the contacts is

observed. Unit of Measure: Millisecond.

• Contact Gap: The distance between a stationary contact and a

moveable contact in the open position.

• Contact Rating (Switching Rating): The capacity to switch

(connect or interrupt) an electrical load. Unit of Measure: Volts,

amps, load characteristic (resistive, inductive, capacitive, power

factor). Contrast with non-switching rating.

• Contact Resistance: The total resistance of the switch,

comprised of the contact interface and terminals. Unit of

Measure: Milliohms.

• Cycles: The number of times a switch can be actuated from one

extreme position to the opposite extreme position and back to

the original position.

• Detent: A mechanical stop that holds the contacts in a given

position after the actuation force is removed or prevents the

changing of contact position at less than a specified actuation

force.

• Detent Angle: The angle or arc between detent positions in

rotary switches. Unit of Measure: Degree.

• Dielectric Strength (Dielectric Withstanding Voltage, DWV,

Leakage Resistance, Breakdown Voltage): The ability of an

insulator to withstand a voltage without arcing across its

surface. Most often applies to insulator between switch

terminals and metal exposed to operator of switch. Unit of

Measure: Volts RMS, Volts AC.

• Dielectric Withstanding Voltage: See Dielectric Strength.

• DIP: Dual-in-Line Package refers to a component with two rows

of PC terminals. The terminals are most commonly on a 0.100"

pitch with 0.300" between rows.

• Double-Break Contacts: A contact mechanism using two sets of

contacts to make or break a given circuit. This provides better

power handling capacity and longer switch life. Typical of high

power industrial switches. See Single-Break Contacts.

• Dry Circuit (Low Energy, Logic Level): An application in

which power levels do not cause arcing, melting or softening of

contacts. Typically requires gold plated contacts for reliable

switch operation. Typical Definition: 0.4VA max. @ 20 VDC

or peak AC.

• DWV: See Dielectric Strength.

• Electrical Life: The number of operations at a given electrical

load that does not result in a degredation of any electrical or

mechanical parameter beyond the standard set by the applicable

end-of-life criteria. Unit of Measure: Cycles (on-off operations)

(rotations).
