Switch design

[Mechmanshan]

Hello, I am building a test stand where I need to be able to switch between solenoids. As it is now the system is set up with three on/off switches, to switch from one solenoid to another you would have to turn off one then turn on another. I would like to have it where when you turn on one switch it turns the others off, ideally only one solenoid would have power at any given moment I would also like to have a master switch than turns them all off.

Thank you in advance.

That would likely be a rotary switch of some sort, assuming your wiring actually has the same voltage, or signal that is directed to one of the solenoids. A single switch in series would disable all of the solenoids

Also consider a multi-pole, multi-throw switch to select between solenoids... wire as needed.

1. Assuming that both solenoids are supplied by the same power source and the current rating is not exceeding say 10A*; it can be easily done by one rotary selector switch. For example with center 0deg "Off" , -45deg "1" and +45deg "2". There are such switches in the market off-the-shelf, at very low cost. Speak/explain to the electrical hardware shops, they should be able to help out.
2. In case the solenoids current exceed say 10A*; you can use the same rotary selector switch to switch on a [contactor] rated for the load.
3. Come back if you still face difficulties. Many of us would be able to help out.
