MRK・MRKC
Key Switches
RoHS Compliant
■Features
1. For PCB Mounting
2. High Contact Reliability
Direct mounting to PC board. The terminal pin layout is
in inch pitch.
Gold-plated contact with self-cleaning, twin contact
mechanism provides high contact reliability.
3. Smooth Operation
4. Improved Resistance to Soldering Heat
Steel ball adopted to click mechanism for smooth operation.
The resistance to soldering heat of contacts is improved by
blocking heat from terminals by using the printed circuit board.
5. Cylinder Lock Type (MRKC)
Cylinder lock mechanism is adopted, enabling choice of
various types of key.
