I need to control a simple relay with a push button; push on/push off. I found this circuit online which seems simple enough except it's for +6-19 VDC. I need to run it with 24-28VDC. It's been a very long time since my basic electronics and semi-conductors training in the Navy. What, if anything, do I need to do to this circuit to use %30 higher operating voltage? Assuming the coil in K1 is a 24 volt coil, can I just raise the value of R3 and R6 to say, 5.6 K or would I need to do more?
