Is 'off' or 'oN' the on or off position?

OFF and ON on machine switches: ON means on, OFF means off. Additional information: 1. Switching power supplies utilize modern power electronics technology to control the ratio of switch tube turn-on and turn-off time to maintain a stable output voltage. A switching power supply generally consists of a pulse width modulation (PWM) control IC and MOSFET. 2. Compared to linear power supplies, the costs of both increase with output power, but at different rates. 3. At a certain output power point, the cost of a linear power supply becomes higher than that of a switching power supply, known as the cost reversal point.
