Overview
|
Ultra-miniature switches are rated at 6 amps at 125V AC and 4 amps at 28V DC. Solid silver contacts. Terminals are gold flashed to inhibit oxidation and to provide easier soldering.
Case material is green diallyl phthalate resin. Bushing thread size: 1/4-40, usable in panel thickness up to 1/4". Micro Switch Co. have discontinued the manufacture of the 8A and 8H type switches, so switches by alternate manufacturers will be furnished. In most instances, Alco switches will be supplied. Switches furnished complete with locking ring and attaching hardware *See Toggle Circuit Table |

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. |

Used this as my off/enable swtich for the anonymous mode of my ads-b. Works great
Received the quantity I had ordered in 3 different shipments .
What can I say, its a toggle switch. works good.
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.

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.
Approximate dimensions of case: 1/2" Length x 5/16" Width x 3/8" Height
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.
Per the manufacturer the size is .039 x .078
This is a DPDT switch.
