Push switch symbol iso10/28/2022 It has also been used in corporate logos, such as for Gateway, Inc. It is often found emblazoned on fashion items including t-shirts and cuff-links. The standby symbol, frequently seen on personal computers, is a popular icon among technology enthusiasts. U+2B58 â HEAVY CIRCLE (Used for IEC 60417-5008 power off symbol).U+23FB â» POWER SYMBOL (IEC 60417-5009 stand-by symbol, IEEE 1621 power symbol). #PUSH SWITCH SYMBOL ISO CODE#The characters are in the 'Miscellaneous Technical' block, with code points 23FB-FE, with the exception of U+2B58 â, which belongs to the 'Miscellaneous Symbols and Arrows' block. In February 2015, the proposal was accepted by Unicode and the characters were included in Unicode 9.0. IEC 60417-5010, the power on-off symbol (line within a circle), is used on buttons that switch a device between on and fully off states.Ī crescent moon, indicating sleep mode, is added by IEEE 1621 as a replacement for the standby symbol.īecause of widespread use of the power symbol, a campaign was launched to add the set of characters to Unicode. Alternatively, under IEEE 1621, this symbol simply means 'power'. This may appear on a toggle switch opposite a power on symbol, alone on a pushbutton that places the device into a standby state, or alone on a button that switches between on and standby. The switch does not fully disconnect the device from its power supply. IEC 60417-5009, the standby symbol (line partially within a broken circle), indicates a sleep mode or low power state. IEC 60417-5008, the power-off symbol (circle) on a button or toggle, indicates that using the control will disconnect power to the device. IEC 60417-5007, the power-on symbol (line), appearing on a button or one end of a toggle switch indicates that the control places the equipment into a fully powered state. Universal power symbols are described in the International Electrotechnical Commission 60417 standard, Graphical symbols for use on equipment, appearing in the 1973 edition of the document (as IEC 417) and informally used earlier. This alternative symbolism was published as IEEE standard 1621 on December 8, 2004. Under this proposal, the older standby symbol would be redefined as a generic 'power' indication, in cases where the difference between it and the other power symbols would not present a safety concern. Proponents include the California Energy Commission and the Institute of Electrical and Electronics Engineers. Standby symbol ambiguity īecause the exact meaning of the standby symbol on a given device may be unclear until the control is tried, it has been proposed that a separate sleep symbol, a waning moon, instead be used to indicate a low power state. Manually operated switch, general symbol Push-button switch (non-locking) Pull-switch (non-locking) Turn-switch (locking) Self-operating thermal switch, break contact Self operating thermal switch break contact of athermal relay Single-pole n-position switch, shown for n = 6 Code IEC/DIN 0113Z03E Description Symbol 07 11 06 07 11 07 07 12 01 07 13 01 07 13 02. Yet the IEC holds these symbols as a graphical representation of a line and a circle. The symbol for the standby button was created by superimposing the symbols '|' and 'o' however, it is commonly interpreted as the numerals '0' and '1'. This standard is still used on toggle power switches. As technology became more ubiquitous, these English words were replaced with the universal symbols line '|' and circle 'o' (typically without serifs) to bypass language barriers. Originally, most early power controls consisted of switches that were toggled between two states demarcated by the words On and Off. The well-known on/off power symbol was the result of the logical evolution in user interface design. Power Button marked with Standby symbol (IEC 60417-5009) turns the device on or off without fully disconnecting power supply
