There are three designs of complementary switches, which means that when the button is closed only one of configurations conducts the current and activates the circuit and the other circuit will remain inactive. On the other hand, this action will be reversed when the button is not closed.
The purpose of these designs is to isolate both VCC and GND. They are not intended to work at high frequencies. Assume that these switches are on/off switches which are intended to connect or disconnect both the VCC and GND of each circuit from the main VCC and GND of the board.
10K resistors are pull up or pull down resistors which prevent the gate of the MOSFET from floating. The 1K resistors are gate resistors which prevent high currents damaging the MOSFET.
Which design is better for this purpose?
If there is a better circuit for this purpose, could you please provide the schematic?
