MK Dose Tactile Switches

The MK Dose is a unique mechanical switch designed for DIY keyboard builders who want dual-action functionality in a single key. It offers a linear feel on the first actuation followed by tactile feedback on the second, enabling two distinct inputs per press. This switch requires a custom-designed PCB with four data pins and is not compatible with standard MX sockets, making it suitable only for users comfortable with custom keyboard assembly.

Feel & Sound

The switch provides a linear initial press that transitions into a tactile bump on the second actuation. This dual-contact design uses true mechanical contacts rather than magnets or capacitive sensors, delivering clear physical feedback between actions. It is not silent and produces typical switch noise without specialized dampening.

Actuation Characteristics

With a total travel of 4 mm and an actuation force around 65 cN, the switch balances moderate resistance and travel distance. The force variance of 10 cN means some variation in feel between units. The two-stage actuation allows for distinct input events, which may benefit users who want multi-function keys or layered commands.

Compatibility

This switch is plate mount only and requires a custom PCB with four data pins to function. It is not compatible with standard MX-style sockets or hot-swap PCBs. This limits its use to custom builds where the PCB is designed specifically for these switches. LED compatibility is unknown.

Trade-offs

Because it requires a custom PCB and is not MX compatible, it is unsuitable for users seeking easy installation or standard layouts. The dual-contact mechanism adds complexity, which may affect long-term reliability or repairability. It is not silent, so it may be less ideal for quiet office environments. Unknown factors include factory lubrication and modification potential.
