The switch features 3 screw terminals for wiring and a 3\/8 inch mounting bushing for installation into a standard panel cutout. Because it uses a push-pull actuator with 3 terminals, it can be wired to control the same circuit from two separate locations, making it useful for setups like dual helm stations or accessory circuits that need switching from more than one point. The chrome plated brass knob and solid brass body give the switch a corrosion-resistant finish suited to the marine environment, and the unit carries an IP54 ingress protection rating for resistance to dust and splashing water. Sierra manufactures this switch to meet or exceed the performance of the original equipment it replaces, and Sierra backs its products with an industry-leading warranty covering posted shop labor, haul-out, towing fees, and related incidental charges. This is a compact, screw-terminal switch intended for straightforward panel-mounted installation rather than a specific engine or drive application.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e MP39400\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type:\u003c\/strong\u003e Push-Pull\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Mode:\u003c\/strong\u003e ON-OFF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e 3 screw terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Bushing:\u003c\/strong\u003e 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Chrome, Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKnob Finish:\u003c\/strong\u003e Chrome plated brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Solid brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIngress Protection Rating:\u003c\/strong\u003e IP54\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 5.9 x 2.5 x 1.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.23 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282190026\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra MP39400 used for?\u003c\/strong\u003e The Sierra MP39400 is a marine push-pull switch used for ON-OFF control of an electrical circuit, and its push-pull design allows the same circuit to be controlled from two separate locations.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many terminals does the MP39400 have?\u003c\/strong\u003e This switch has 3 screw terminals for wiring connections.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size mounting hole does the MP39400 require?\u003c\/strong\u003e The Sierra MP39400 uses a 3\/8 inch mounting bushing, so it is designed for a panel cutout sized to that bushing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the MP39400 switch made of?\u003c\/strong\u003e It is constructed of solid brass with a chrome plated brass knob, giving it a corrosion-resistant finish suited to marine environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this switch control a circuit from two locations?\u003c\/strong\u003e Yes, the push-pull design of the Sierra MP39400 lets it be wired to control the same circuit from two separate locations.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Sierra MP39400?\u003c\/strong\u003e The switch measures 5.9 x 2.5 x 1.3 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the MP39400 weigh?\u003c\/strong\u003e The Sierra MP39400 weighs 0.23 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the MP39400 rated for water or dust resistance?\u003c\/strong\u003e This switch carries an IP54 ingress protection rating, meaning it resists dust ingress and splashing water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the MP39400 meet OEM performance standards?\u003c\/strong\u003e Sierra manufactures the MP39400 to meet or exceed the performance of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat operation mode does this switch use?\u003c\/strong\u003e The Sierra MP39400 operates in ON-OFF mode via its push-pull actuator.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra MP39400?\u003c\/strong\u003e The UPC for the Sierra MP39400 push-pull switch is 808282190026.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the MP39400 covered by a warranty?\u003c\/strong\u003e Sierra backs the MP39400 with an industry-leading warranty that covers posted shop labor, haul-out, towing fees, and related incidental charges.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988454781147,"sku":"SIE-MP39400","price":11.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-MP39400__58648.1722494802.500.750.jpg?v=1785188458","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-mp39400-marine-push-pull-switch-3-screw-terminals-3-8-bushing-replaces-cole-hersee-m-641-01-m630","provider":"Good Vibes Marina","version":"1.0","type":"link"}
