Lever/Circuit Relationship

LEVER/CIRCUIT RELATIONSHIP

The operating sequence above is repeated in multipole devices. Each pole has double-throw circuitry and consists of three terminals which exit at the bottom of the switch case. The keyway is a helpful reference when you are applying a switch with the momentary (ON) circuit at one of the extreme lever positions.

Nice, well-made switch. I gave it four stars because what these really need is a backshell. Unused terminals create a potential short hazard if something conductive falls out of place behind the panel. Something as simple as a Mocap flexible vinyl cover with a hole for the wires to pass through would make these a five-star product.

Q: I just need a micro to switch between nav 1 and nav 2. I'm assuming I need the on/on, what's the difference in the only two you offer

The difference is the ability to turn both Nav's off. You do not want this feature to cause accidents so part number 11-04231 will be best for your situation.

Q: What are the switch case dimensions of part # 11-04231: Length, width, depth?

Approximate dimensions of case: 1/2" Length x 5/16" Width x 3/8" Height

Q: The circuitry shows on-off-on and on-none-on. What does the none mean. Im looking for a on-both-on switch.

None means that there is no position. For example, if the switch is on-none-on, it will have no center position. It toggles from on to on.

Q: What size wire terminals are used for these switches?

Per the manufacturer the size is .039 x .078

Q: Part number 11-04234 says DPST, looking at the spec for MTA206N it looks like it should be a DPDT?

This is a DPDT switch.
