Physical switch + relay + arduino nano looking for a sketch - Need

Hello, I’m using a Arduino nano to control my 3 relays I have added an switch which should turn all relays on when switched on. I’m hosting my own blynk server and I need help with making a sketch. I have only a little bit of experienced with coding for the Arduino. wiring schematics: parts: Arduino nano ENC28J60 Ethernet shield 2x 5v power supplies 1x 1 channel relay 1x 2 channel relay 1x toggle switch I’m currently using the example sketch for enc28j60 /*******************************
