You cannot easily automate the manual switches so you need to use Voltage Controlled Switches. You need to: 1) Read the Simulation Tutorial, (3) (All of it!) in (2) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a)<br> <br> especially study the section and examples on Voltage Controlled Switches. 2) Then look at this sim (which you will not be able to run until I fix it for LTspice): [https://oshwlab\.com/example/How\_to\_simulate\_a\_DPDT\_switch\-Wgs2CbLlH](https://oshwlab.com/example/How_to_simulate_a_DPDT_switch-Wgs2CbLlH)<br> <br>
