I need a circuit that gives momentarily contact when I close a switch and will give another momentarily contact when I open the same switch again.So when I switch a switch on there must be a circuit that acts as a push button switch and when I switch that switch off again it must act as another separate push button.I have a device that switches on with a push button and switches off with another push button. I want to switch the device on and of with a thermostat by using a circuit that connects the thermostat to those two push buttons, so that i can still use them to switch the device if I want to.
