This is what I've come up with so far. The big blue area at the bottom is the latch so I can't put anything there. Everything should be to scale.
Since some things are blurry, here's what everything is:
Top row - main power switch (probably key switch) with indicator light, volt meter, e-stop, amp meter, alarm indicator light (lit when alarm is set) and light/buzzer combo.
Middle row - HLT element switch with indicator light (lit when switch is on) and red light to indicate when power is actually going to element, HLT PID with alarm switch, MLT PID with alarm switch, Timer with alarm switch, BK PID with alarm switch, BK switch/lights same as HLT.
Bottom row - pump switches with indicator lights. I was thinking about putting a logo between the pump switches by either using something magnetic (is this a bad idea??) or just having two small hooks to hang a nameplate on.
Am I missing anything? Anything you would recommend changing? I have the space to add more stuff. I just wasn't sure what else to include and don't want to just fill the panel for the sake of filling it.
