Why would putting the switch between the Light and ground be dangerous when changing the light bulb? The switch used in this case is a single pole, single throw (SPST). Here is a schematic for a circuit where the switch is used to connect a light bulb to the dc power supply. Operation of a Switch Typically, switches are used to connect and disconnect parts of one circuit with other parts of a circuit. However, the MOSFET has to move through the pinch-off/saturation region to get between these two regions of operation.The modes of operation are the cut-off and triode/saturation regions. In digital electronics as well as power electronics, the primary use of a MOSFET are as a switch that connect and disconnect the circuitry at the drain of the MOSFET with the circuitry at the source.They are found in high speed and/or high power amplifiers, oscillators, current sources, etc. ![]()
