LA19 Manual Electric Whistle Button
Product Description
LA19 Manual Electric Whistle Button
Product Introduction
The Manual Electric Whistle Button is a critical, user-initiated control device designed for the direct and immediate activation of a ship's electric whistle or horn system. Engineered for simplicity, durability, and fail-safe operation, this button provides the vessel's crew with a reliable means of generating mandatory sound signals as required by international regulations (SOLAS, COLREGs). Its primary function is to ensure clear and prompt communication during navigation, maneuvering, and in emergency situations.
Rugged Marine-Grade Construction
Built to withstand the demanding conditions of the maritime environment, the button features a robust housing typically constructed from corrosion-resistant materials such as marine-grade stainless steel or brass with a protective finish. It boasts a high Ingress Protection (IP) rating (e.g., IP66/IP67), making it fully waterproof, dustproof, and resistant to salt spray, oil, and UV exposure. The internal switch mechanism is designed for high electrical load capacity and long-term reliability under frequent use.
Intuitive Operation & Clear Feedback
The button is designed for instant, unambiguous operation. It often features a large, ergonomic actuator cap (commonly red or black) that is easy to locate and press, even with gloves on. A distinct tactile feel and/or an audible click provides positive feedback to the operator upon activation. Many models integrate a built-in, highly visible indicator light (LED) that illuminates when the whistle circuit is energized, providing clear visual confirmation that the signal is being sent.
Easy Integration & Versatile Application
This momentary-contact button is designed for straightforward integration into a vessel's 24VDC or 110/220VAC electric whistle control circuit. It is commonly installed in critical locations such as the ship's bridge console, bridge wings, and engine control room for immediate access. As a fundamental component of the ship's signaling system, it offers a dependable, direct-control backup or primary interface, ensuring the crew can always command the vessel's audible voice as needed for safety.
