MOSFET pair makes simple SPDT switch

Yes, a MOSFET pair can be used to make a simple SPDT (Single Pole Double Throw) switch. This type of switch allows you to select one of two different signal paths.

To make an SPDT switch using MOSFETs, you would need two MOSFETs and a few other components such as resistors and capacitors. The MOSFETs are connected in parallel, with one acting as an "on" switch and the other as an "off" switch. By controlling the gate voltage on each MOSFET, you can select which one is turned on and which one is turned off.

It's important to note that the MOSFETs should have a low on-resistance to minimize signal loss. Additionally, you may need to add additional circuitry to protect against overvoltage and overcurrent conditions.
