Switches itself off after 30 seconds

My Mac was running very slow (kept getting multi colour timer for everything) so I decided to switch it off then back on. During switch off it 'hung'. I pressed the Control-Alt-Del equiv. It switched off, but now when I try to switch it on I get the grey screeen, apple symbol, timer then after approx 30 seconds it just switches itself off. Have I killed it? Please help...

The MacBook Air is not known to be susceptible to the bad capacitor issue, which concerned capacitors that Apple used four and five years ago.
You are not seeing a kernel panic, because you have not reported the gray overlay screen with a message in multiple languages.
I would recommend against reloading your system or having your logic board replaced without attempting several much less invasive potential solutions.
The first potential solution I would pursue is to reset the power manager on your MacBook Air. From a powered-down state, connect the AC power cable, then while holding down (left) shift-control-option, press the power button once. Wait five seconds, then press the power button to start the computer.
If that doesn't fix the problem, try the following:
Disconnect all external peripherals. Make sure you are not running your computer on a soft surface (overheating).
If the sleep indicator light briefly illuminates just before the system shuts down, you will need to have a technician check the thermal sensor connection to the logic board.

Using the original system discs and an external USB optical drive, run the Apple System Hardware Diagnostic on your MacBook Air. If error codes are reported, take them in to a technician.

There are other tests that can be done and logs that can be checked by a technician. If your computer continues to give you this trouble despite trying the above steps, you might do best to bring it in.

You haven't killed it, you have crashed your system. Go through the web, search for the reinstall codes for your system. The thing is that every MAC has it's own codes (based on the which system you used) that can reinstall your system, without loosing any of your data. During the new installation it asks you if you want to save all the data you had, and then you can start using your MacBook from the begining

Trouble wiring timer

If these lights are on 2 way switch you are going to have to figure out which wire runs to your outside lights. If you aren't familiar with 2 way switches here's a link to a site that will help:

If you look at the diagrams on this site, you will see that ONE of the switches has a wire that runs to the light. I don't know which switch this is in your case.

You also need to decide if you want to be able to override the timer with the switches. Also, please confirm that the switches are 2 way (meaning that you can always turn on the lights from either switch). Sorry I couldn't explain more but I need to know whether the timer has complete control over the lights or if you want the switches to override the timer.

It might be a little trickier than you might think. Good luck and be careful.

Electric washing machine

to make sure of the time that the device will switch on/off or cycle
in use the armature rotates approximately 1 rev/hour, slowed down by a multi stage gearbox, & multiplied in force by the same factor
the switches are 1/2 ounce pressure,
there is no difficulty with timer motor being able to move the switches
do not file them 'smooth' it causes difficulty with program shifts
(have done it, once, only once, never again)

Kvm switch won't stay on second computer, switches back

You might try disabling any power saving schemes in use on either computer. The KVM (I believe) gets its power through the ports and one computer may be shutting down power.
