Discover 5 Tips For The Tuttnauer 2540M Autoclave Door Switch & Acitvator

5 SERVICE TIPS FOR THE TUTTNAUER 2540M AUTOCLAVE DOOR SWITCH/ACTIVATOR

As a safety feature, Tuttnauer installed a Door Switch on their 2540M Autoclave. The Door Switch has a button on it that must be depressed in order for the autoclave to function.

If the door is open, or the Door Switch is defective, you will not get any heat

The Door Switch is located behind the face plate on the side where the Closing Device is located.

Here Is Where You Will Find The Tuttnauer 2540M Doow Switch & Activator

How the Tuttnauer 2540M Door Switch Activator Works

When you close the door on your autoclave, the door switch activator pushes the button in on the door switch. This switch acts like any other ordinary switch. And like turning a a light switch on: when the door is closed, the button on the switch is depressed by the Door Switch Activator, and allows the electricity to flow through to the heating elements. In effect, this action turns the heating elements “ON”

5 Tips On Adjusting the Door Switch Activator on the Tuttnauer 2540M Autoclave

Note: The Part Numbers listed below are from AllClaveParts.com

  1. The Heat-On light and heaters should come on when the door gasket comes in contact and is completely sealed with the chamber surface – and not before that. Listen for the clicking sound of the door switch at this time.
  2. The Door Switch Activator (Part #TUAO66-1754) is a spring loaded activator that can be adjusted by tightening or loosening the screw. Adjustments must be made so that when the door is closed and the final turn of the door closing device has been reached, two things will happen: 1) you will hear the door switch “click”; and, 2) you will see the Heat-On light go on (which means that the heaters have been activated)
  3. The Door Switch (Part #TUS014-1785) also can be adjusted to activate the heaters by adjusting the positioning of the rear inside panel nut, bringing the switch closer to or farther away from the activator. This would be necessary only if the sterilizer does not come equipped with the spring loaded activator ver.3.
  4. Use of the Rubber Boot offered by AllClaveParts (Part #TUB072-1759) for the door switch may prevent early switch failure by protecting the switch from steam. Make the necessary adjustments to the activator or the door switch after you have installed the boot.
  5. Don’t forget – when replacing an old door gasket with a new one, recheck the positioning of the door switch and activator, then make any necessary adjustments, and always check for steam leaks around the door with each of the above steps.
