Simple solenoid kicking mechanism for your robotic/automation project.

Circuit diagram: https://goo.gl/7zy8vR.

If you want to activate the kicker using wireless RF remote relay module, then use this circuit: https://goo.gl/CFRWC2. It is combined with a micro switch for local activation feature and the best part is, both of the relay and switch are working together to cut the supply from ZVS capacitor charging module to prevent back current when either one is pressed/triggered. When both are idle, they will make sure the loop to the capacitor is always established to ensure the solenoid activation is always ready.
