Excellent 25 Amp (DC), 15/32 switch. Sturdy and comes with all the right hardware.

Well made, better than the factory switch it is replacing. Would buy again. My only gripe is aesthetic, the toggle is a dull finish instead of a polished metal finish. It looks a bit industrial in the cockpit. On the upside, the dull finish provides better grip.

Great toggle switch. A little pricey but it hard to find good reliable AN class toggles at the price AS offers. A little more in the drawing and description department would be helpful.

Switch appears to be fine. I didnt see any dimensions and took a chance. I is way too big for my use as a control wheel trim switch. I guess that I will need to eat it, since it was my bad.

Q: What Amp rating is the AN3027-2 switch?

This is a 20 amp switch.

Q: Does the AN3021-2 measure approximately 1-1/8" x 5/8"?

Yes, these are the approximate dimensions: 1-1/8" L x 5/8" W x 5/8" H.

Q: When the chart shows "None" in a given position (e.g. center position), does that mean that the switch does not have that position? In my example, with None in the center position, the switch just moves from On for Up to Off for Down?

Correct. With "None" in the center position, the switch will toggle only all the way up to all the way down.

Q: MS35059-27 is described as momentary on in both on positions, does that mean that the switch lever is spring loaded and stays on as long as it's held in one of the on positions?

Yes, push the lever to either position to activate, and the lever will spring back to center off, if not held in position.

Q: Are these Toggle Switches acceptable for 14V dc system?

Yes, these switched will work in 14v dc systems.

Q: What is the hole size of the SPST toggle switch?

The hole size for the toggle switches to fit through the panel is 1/2".

Q: What does the asterisk mean in ON* for these toggle switches?

The * represents momentary on. Essentially it's on at contact and then once released it is back off. It does not stay on.

Q: On which side of the switch does the mounting hole keyway slot reside? Is it on the up/on side or the down/off side? I am laser cutting mounting holes and want to be sure the panel tooth is aligned properly for the switch slot.

The keyway slot is on the down/off position.

Q: How do I order quantity 12 of MS35059-23 toggle switches?

Enter 12 in the input box in the "Buy" column in the ordering grid. Then, click the "Add to Cart" orange button below and the items will be instantly added to the shopping cart.

Q: Do the switches include hex nut, lock washer and key washer?

Yes, included are 2 hex nuts, 1 lock ring, and 1 lock washer.
