Copal MRKC1031A-R-01B-Z Key switch Datasheet

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