    Switch
In summary, the person is looking for a selector switch that can choose between a CD drive and a cassette player motor, with an option for an off position. They need a Double Pole Double Throw Centre-Off type switch, and are requesting a picture and wiring diagram. The person providing the answer will sketch it out later on a different computer.

hello every one
i was wondering what type of switch should i use if i wanted to use two items namely a cd drive and a cassette player motor. both of them are connected to two separate power supplies which means two positve wires and two negative wires. i want to use that type of selector switch which can select between the cd drive and the motor and one selection for off position.
can anybody advise and also send me a pic and wiring diagram of the switch if any.
thanks

You need a Double Pole Double Throw Centre-Off type. Turning it one way will connect wires A & B together. The other way will connect wires C & D. The middle position leaves no contact at all.
I'll get into Paint in a while here and do up a sketch.

edit: No I won't. W's machine, which I'm working on now, doesn't have it. It'll have to wait until I can do it on the Mac and transfer it over to post.

There are a few different options for a switch that can control both a CD drive and a cassette player motor. One option could be a single-pole double-throw (SPDT) switch, which has three terminals and can connect one input to either of two outputs. Another option could be a double-pole double-throw (DPDT) switch, which has six terminals and can connect two inputs to either of two outputs.

In terms of wiring, you would need to connect the positive and negative wires from each device to the corresponding terminals on the switch. The remaining terminal on the switch would be connected to the power supply. When the switch is in the "off" position, neither device will receive power.

As for a wiring diagram and picture, it would depend on the specific switch you choose. I suggest doing some research and finding a switch that fits your needs and then looking for a wiring diagram and picture for that specific switch. You can also consult with an electrician for further guidance and assistance. Best of luck with your project!
