Mini Microswitch - SPDT (Roller Lever)

The Sparkfun KW4-Z5F Roller Microswitch is a compact and powerful component, capable of controlling a wide range of electrical loads. It's a versatile device, suitable for both logic level circuits and power duty switching applications up to 16.1 A and 250 Vac. Despite its robust capabilities, the microswitch is incredibly compact, with an overall length of less than 20 mm.

This microswitch is designed with a nylon 66 housing and brass terminals with silver plating for optimum durability and conductivity. It features a single pole, double throw (SPDT) contact configuration and is rated for 5A 250VAC / 10A 125VAC. With a contact resistance of less than 30mΩ and insulation resistance of more than 100mΩ (500VDC), it guarantees reliable performance.

The roller lever design enables smooth switch operation, with an OFF - momentary ON functionality. It can operate within a wide temperature range of -25℃ to +85℃, and can sustain an ambient temperature of less than 85% RH. This makes it a suitable choice for various environments and applications.

The Sparkfun KW4-Z5F Roller Microswitch is not just about performance, but also about longevity. It boasts an electrical life of more than 10,000 cycles and a mechanical life of over 100,000 cycles. With its EU "CE" certification, you can be assured of its compliance with safety standards.

Whether you're working on a computer-based circuit or a power-duty switching application, this microswitch is an excellent choice. Its compact size makes it an ideal fit for projects where space is at a premium, while its robust features and durability ensure it can handle even the most demanding tasks.
