Rocker switches, also known as rocker switches and paddle switches, are highly reliable, inexpensive devices commonly used to control the operation of electromechanical devices. WR19AL rocker switch is a time-delay type, which is widely applied in many different applications. This article discusses the application field and working principle of WR19AL rocker switch.

Applications: WR19AL Rocker Switches are mainly used in automotive, maritime and industrial applications. In the automotive sector, they are used in dashboard light panels, dashboard rearview mirrors and rear defroster fan controls. In maritime applications, they are used in navigation control systems, marine diesel engines and shipboard instrumentation. Furthermore, they can be used in electromagnetic starters, disinfection systems, automatic control systems, sound and light alarms, door locks, home automation systems and so on.Working Principle: WR19AL rocker switches provide single pole, double pole and three-pole configurations in a range of sizes, as well as a choice of SPST, SPDT and DPDT switch mechanisms. It has the characteristics of dustproof, water-resistant and flame retardant. The switching action is initiated by manually pressing down on the switch rocker, which causes contacts to close, supplying power to the circuit. When the momentary pressure on the switch is removed, the metal chamber inside the switch opens and releases the return spring, allowing the contacts to open, breaking power to the circuit. This design prevents an overload of electrical current and potentially dangerous short circuits.The WR19AL rocker switch is designed to accommodate a maximum current of 10A and a maximum voltage of 250V. The switch is designed to handle an initial surge of electrical current up to 20A, but the switch can only handle the surfeit of current for a short period before it must reset. The WR19AL rocker switch has a built-in anti-submarine function, which will trip the switch if it is submerged in water. The switch will remain in the open position until it is reset by manually pressing down on the rocker.Conclusion: WR19AL Rocker Switches are highly reliable, inexpensive devices commonly used to control the operation of electromechanical devices. Its versatility and robust design make it ideal for use in a variety of automotive, marine and industrial applications. WR19AL rocker switches provide single pole, double pole and three-pole configurations in a range of sizes, as well as a choice of SPST, SPDT and DPDT switch mechanisms, with a maximum current of 10A and a maximum voltage of 250V. They are also designed with a built-in anti-submarine function for added protection against water damage.
