This is my first post here and i was wondering if anyone could help me. I am trying to create a system that will enable me to connect nine or ten 240v devices but only run one at a time. if one in the system is on and another one is switched on the first one will turn off. Is there a simple way to achieve this? I've been searching Google for the last five hours with no success. I'm not sure what I should be searching for or what kind of design can help me achieve this.
I found this on YouTube but I got stuck trying to expand the amount of switches and bulbs.
Thanks for you help.
Hi there. Thank you for the comments. I could do this with a simple rotary switch but I was looking for a solution that was spread out to each device. To give a little more context each device would actually be controlled by a NVR (no-volt release) switch. If we take the example of the YouTube video. And did each switch with an NVR. Then the system would reset its self when ever one of the switches where activated. Why this is useful is so that if the devices are spread out then they can be activated in the knowledge that if another one was on it will be turned off and reset.
And to answer some questions.
Homework? Sorry, this is for a small woodworking business.
The point of this system is not to overload current draw on the main breaker board. If two of these devices are run at the same time then they will trip the system. There is no way to expand the current rating on the main board so this is the only solution to keep the system from tripping out. The devices are power tools (table saw, spindle moulder, lathe etc...) and have been installed with soft starting modules (this is so that peaks don't trip out the breaker board on there own) so it's not that critical that they end and start microseconds together.
Do you know of a way or formula to expand that switch circuit in the video?
