- Curved screw connection for small DIY modules. Easy to install with screw terminals for secure, tidy wiring and practical mounting. - Car ignition key. Built with high quality metal materials and IP65 waterproof protection, suitable for wet or dusty environments. - Start Switch Panel. Diameter phi 16 mm; breaking capacity 3 A at 250 VAC. Compact and robust for compact control panels. - Engine start button. A momentary push button that changes the circuit state only when pressed. An automatic mechanism such as a spring returns the switch to its standard position immediately after activation, restoring the original state of the circuit. Usage scenarios - Ideal for small DIY electronics projects and control panels that require a compact, reliable start input with easy wiring and secure screw connections. - Suitable for outdoor or harsh environments, including wet or dusty settings, where IP65 protection is important, such as workshops, boats, or weather-exposed enclosures. - Useful in automotive-inspired or prototype applications where a momentary start action is needed, such as dashboard simulations, remote start prototypes, or equipment that requires a temporary activation signal.
