Thermal Flasher

Thermal flashers are a type of relay that are commonly used in automotive applications. They are designed to control the flashing of turn signals and hazard lights in vehicles.

Thermal flashers work by using a bi-metallic strip that heats up when current flows through it. As the strip heats up, it bends and breaks the circuit, causing the lights to turn off. As the strip cools down, it straightens out and completes the circuit again, causing the lights to turn back on. This cycle repeats, creating the flashing effect.

Thermal flashers are preferred over electronic flashers in some applications because they are simple, reliable, and do not require additional components such as capacitors or resistors. They are also less sensitive to voltage fluctuations and can work with a wide range of input voltages.

In summary, thermal flashers are a type of relay used in automotive applications to control the flashing of turn signals and hazard lights. They are reliable, simple, and do not require additional components.
