The line symbol means “power on” and the circle symbol means “power off”. The presence of both (I/O) on a push button means the switch toggles the power.
Is the O or line on or off?
(1 or | means on.) IEC 60417-5008, the power-off symbol (circle) on a button or toggle, indicates that using the control will disconnect power to the device. (0 or ◯ means off.) IEC 60417-5009, the standby symbol (line partially within a broken circle), indicates a sleep mode or low power state.
Which way is on and off on a switch?
An easy way to remember: 0 = false, meaning no power or off; and 1 = true, or on. (In the case of I/O, the ‘I’ represents 1.) So, if a switch is turned to I, it’s in the On position. If it’s turned to O, it’s in the Off position.
What symbol means on and off?
IEC 5010, the power on-off symbol (line within a circle), is used on buttons that switch a device between on and fully off states. IEC 5009, the standby symbol (line partially within a broken circle), indicates a sleep mode or low power state.
What is on on switch?
The ON-NONE-(ON) or ON-(ON) circuit is a momentary, double throw, two-position switch circuit. In general, for basic unlighted single pole switches, the maintained ON position closes the circuit at switch terminals 2 & 3, and the momentary ON position closes the circuit at switch terminals 1 & 2.
What is a on off switch?
1. on-off switch – a hinged switch that can assume either of two positions. on/off switch, toggle switch, toggle. DIP switch, dual inline package switch – (computer science) one of a set of small on-off switches mounted in computer hardware; used in place of jumpers to configure the machine for a user.
What is the symbol of switch on?
The switch symbol in the ON position is represented by two small circled connected by a straight line. When a switch is on, it completes the circuits and the current can flow.
Is on none on the same as on off on?
“On-Off-On” indicates the switch can rest in a middle position between connections; “On-None-On” indicates there are only two rest positions, making one connection or the other. “On-None-(On)” means one of these positions is actually momentary.
