which are under electric tension and are associated with each other and a metal
foil which is superimposed on the touchable metal parts which are in contact
with the base insulation. Quality of nonconducting material to withstand a
maximum voltage
Differential
Distance (or angle) from the operating position to the release position
Diode element with 1 diode
1 blocking diode for free connection i.e: for lamp testing in an element block
Diode element with 2 diodes
2 blocking diodes for free connection i.e: for lamp testing in an element block
Double break
Contact, in which the two disconnection points of the circuit are present
Double pushbutton
2 independent pushbuttons in a single switchgear device
Double pushbutton actuator
Front part of a Double pushbutton, without Switching element
Double-Break
A mechanism which breaks the circuit at two points simultaneously
Double-Throw/Changeover switch contact
Contact arrangement that alternately transfers normally open and normally
closed circuits. Contact made of a combination of NO (Normally Open) and NC
(Normally Closed) contacts, with 3 connections (Break-make contact)
Electrical Life
Wear-resistant property of a switch under a specified electrical load, expressed
in numbers of actuations. Expected cycle life when switch is operated at full
rated load
Element block
Unit with integrated function parts i.e: Lamp transformer
EMC
Abbreviation for electromagnetic compatibility
Emergency stop pushbutton actuator
Front parts of an Emergency stop button, without switching element
Emergency stop pushbutton with key-release
For the switching off of current consumers, which could endanger persons,
animals and property. Generally the activation surface is mushroom-shaped.
Unlocking occurs by means of an insertable key into the Operation part
Emergency stop pushbutton with twist-release
For the switching off of current consumers, which could endanger persons,
animals and property. Generally the activation surface is mushroom-shaped.
Unlocking occurs by twisting the Operation part. The Contact must automatically
open the circuit
Emergency switching element
Switching element with a guided NC contact
EMI
Abbreviation for electromagnetic interference
ESD strength
Static electric strength (kV) between operation part and conducting material of
the Switchgear (contact, terminal)
Fixing nut
For fastening the device in the front panel
Flashing frequency
Pulses per time unit in Hz
Flashing indicator
Indicator with integrated flashing device
Flush mounting
Almost flush installation of the pushbutton in a front panel
Foolproof (emergency stop pushbutton)
Protection against accidental actuation. Chance or intentional manipulation
(inching operation) is impossible
EAO Switch Condensed Catalog 100
Forced opening
IEC 947-1 para. 2.4. 1 0 => Opening movement which ensures that the contacts of
a Switchgear have reached the "open position" if the operation part is in the
OFF position
Free Position
Initial position of an actuator when there is no external force applied on the
actuator and the contacts are in the unoperated condition
Frequency (sound)
Amplitude of oscillation of the sound of an acoustic signaller, expressed in Hz
Front bezel set for flush mounting
Accessory part for "Flush mounting"
Guided motion
Connection between Operation part and Contact, which has the effect of directly
transmitting (without spring parts) the force exerted on the operation part on to
the contact
High Inrush
Loads that require more current when first turned on than needed to continue
operation. Light bulbs exhibit high resistive inrush and may draw up to 10 times
or more the normal operating current when first turned on. Motors may show
high inductive inrush currents when started
Illuminant
Light source for the illumination of the Lens or Indicator cap i.e: filament lamp,
LED, neon lamp
Illuminated pushbutton actuator
Front part of an illuminated pushbutton, without contacts
Illuminated pushbutton maintained action
Pushbutton (maintained action) with integrated lampholder
Illumination
The illumination of an indicator area or of the operating part of an
illuminated pushbutton by means of an illuminating device (filament lamp, LED,
neon lamp)
Indicator
Light signal indicating a state by being illuminated or extinguished
Indicator actuator
Front part of an Indicator without integrated lampholder
Indicator cap
Transparent, also colored, cover for an Indicator
Indicator element
Unit with integrated lampholder for mounting an Illuminant
Insulation resistance
DIN EN 61058 T. 1 (VDE 0630 T. 1 ) para. 15. 1 => Resistance (kOhm, MOhm)
between the different poles of a switch (base insulation) and between all parts
which are under electric tension and are associated with each other and a metal
foil which is superimposed on the touchable metal parts which are in contact
with the base insulation. Quality of nonconducting material to withstand a
maximum voltage
Insulation socket
Protection against contact of the live part of the blade terminal socket
Interval frequency
Oscillations per time unit in Hz
Keylock switch
Switch with a key as operation part
Keylock switch actuator
Switch actuator (without contact) with a key as operation part
Knob
Operation part for the activation of the Selector switch
Lamp connection (technical component designation)
Designation of the Connection method (i.e: Screw terminal)
Lamp element
Unit with integrated lampholder for the mounting of an illuminant
