Product Details

The Sierra MP39300 is a momentary push-button switch designed for marine applications including fog horns, sirens, and other momentary-contact electrical functions. Built with a chrome-plated brass housing, this compact and durable switch delivers reliable performance in demanding on-water environments.

Key Features:

  • Switch Type: Momentary On/Off — SPST (Single Pole, Single Throw)
  • Housing: Chrome-plated brass construction for corrosion resistance
  • Button Style: Black plastic push button
  • Mounting Stem: 1-3/8" L x 5/8"-32 threaded mounting stem
  • Terminals: 2 screw-boss terminals for secure wire connections
  • Overall Width: 2-5/8"
  • Rating: 12V DC / 35 Amps
  • Intended Use: Fog horns, sirens, starters, and other momentary 12V circuits

The MP39300 installs easily through a standard panel cutout using its threaded mounting stem and secures with the included chrome face nut. Its momentary action means the circuit is only active while the button is depressed — ideal for horn and signal applications. A proven choice for marine electrical panels and console installations.

Looksgood on the website...

Good job.

Great so far!

Ordering was easy, over the phone or online i was able to find all my parts on Autoplicity conveniently and my order was shipped out in a timely manner. I had concerns that were tended to by a quick phone call and great customer services reps.

5 minute ordering process, faster than going to the auto parts house. Everything went as Autoplicity indicated. I ordered on Saturday, order was processed on Monday, item was shipped on Wednesday(tracking info for UPS was emailed on Wednesday), item was r

I received excellent customer service from Autoplicity. I emailed them a question about my order and received an answer within an hour or so. I was very happy with this company

Very easy mobile site!

Autoplicity got my air filters shipped next day after I placed my order. Cheap prices, and good customer is what they stand for. I will definitely be looking at their site in the future for my car needs. <br>

easy

Very pleased with the ordering process. Did lots of research on the product I ordered and autoplicity was able to beat the price of any local carrier of this product by $80. Even better that they offered free shipping because it is a heavy item.

Searched local and web stores for an Exedy clutch kit. Even with shipping, Autoplicity beat the others on price. They are an Amazon seller so I was not as concerned about buying from them as I usually am when buying things on the web.

Nice website, easy to use.

Good

PART CAME IN FAST!!! Can't wait to tear it open
