The Goobay MS 243 LC is a subminiature toggle switch with 2 pins, designed for use in compact electronic devices and assemblies. The device features a blue housing and a metallic lever that enables the switching function. The switch is designed for operation in two positions: ON and OFF. It is used in the electronics and model building industries, where small dimensions and reliable switching performance are required.

Applications

The switch is particularly suitable for applications in the DIY and model building sectors, where space constraints and clear operability are important. Due to its compact design and robust construction, it is also usable in smaller electronic devices, such as controls for model vehicles or in self-built devices. The maximum load capacity of 3 A at 125 V or 1.5 A at 250 V makes it suitable for a wide range of applications in low-voltage technology.

Functions and Equipment in Detail

The switch features two solder terminals, enabling easy mounting on printed circuit boards. The lever is made of metal, ensuring high mechanical stability and longevity. The switching position is clearly visible, as the lever is locked in the ON and OFF positions. The electrical life exceeds 10,000 switching cycles, indicating high reliability. The contact resistance is maximum 20 mΩ, ensuring low energy loss. The insulation resistance is at least 1000 MΩ, ensuring safe electrical isolation.

Technology Explained Simply

The switch operates on the principle of a mechanical toggle, where the lever movement opens or closes the electrical connection between the two pins. The maximum operating temperature is +85 °C, and the minimum temperature is -25 °C, allowing use in a wide range of environments. The dielectric strength of 1000 V for one minute demonstrates the high insulation quality of the switch. The dimensions of 8 mm length, 5 mm width, and 7 mm height make it a very compact component that fits into tight spaces.

Compatibility and Accessories

The switch is designed for mounting on printed circuit boards and can be processed with standard soldering irons. It is available in blue, making it visually easily identifiable. Its use in combination with other components, such as resistors or transistors, is possible as long as the electrical load limits are not exceeded. The specifications for maximum load capacity (3 A/125 V or 1.5 A/250 V) are crucial for selecting the appropriate application.

Mounting and Installation

Mounting is done by soldering the two pins to the corresponding traces on the board. The solder terminals allow for a secure mechanical and electrical connection. The switch can be mounted in various orientations, as the ON and OFF positions are clearly defined by the lever. It is important to ensure that the switch is not subjected to mechanical stress to guarantee its service life.

Advantages in Operation

The switch provides a clear and precise switching function with low contact resistance, leading to efficient current transfer. The high electrical life and robust metallic lever ensure a long service life. The compact design allows flexible placement in tight spaces. The operating temperature range of -25 °C to +85 °C permits use in a wide range of environments, from indoor installations to outdoor areas with moderate temperatures.
