Function, fit and feel is great. LED adds more value for night boating.
This switch is the proper way to install an electric windlass on your boat. Many folks don't understand that a windlass installation (high current) should go through a windlass relay, and not the switch. Many installers try to attach the switch directly to the power of the windlass. This switch simply supplies the control to activate the relay. The LED on this up/down switch is perfect for night boating. The switch has a good feel and seems to be high quality. My windlass is installed with this switch and functions fine.

Great replacement for Simplicity Height-of-Cut Switch
The OEM electric height-of-cut switch for the Simplicity mower deck developed carbon deposits on internal contacts over time due to arcing, making the switch intermittent, ultimately failing after about 3 years of use. The OEM replacement part (1761475YP) goes for $30-40, and fits a number of Simplicity/Snapper/Murray mowers. The Nilight momentary up/down switch (90251B-A) seems to be an excellent replacement for much lower cost, and adds the LED function as a bonus. Do not plug the switch directly into the connector used for the OEM switch, but using the included wiring harness with the "Wiring Method B" diagram in the instructions, simply plug the individual wires into the corresponding connection terminals of the the old connector as I did and it will work perfectly. Your connector may be wired differently, so you will need to determine which terminals in that connector are +12V from the battery, ground, and the two wires leading directly to the DC motor on the mower deck. See photos. I added identifying numbers and insulating shrink tubing to the wire end terminals to improve the overall installation a bit (it's what I do). Time will tell how long this switch holds out in this application, but even if I have to replace it again in 3 years, less than 10 bucks is better than 40! Note that this is an independent review, I purchased the switch directly and have not been compensated in any way.

Works well
Good quality switch. I used to bypass a bad body control module and wire a window motor directly. Saved me hundreds doing it this way.
