Hi All,
made a high side switch but it does not work quite how i want. I want a "snap" action from the switch. When the zener conducts the switch should be closed and when its not conducting open.
The circuit does this but its not very accurate. I am using a 9.1V zener but the switch actually works at around 9.6 to 9.7V. I want it to work as close to 9V as possible.
Can anyone suggest some improvments?
Thanks
