Cherry switches (Hirose) are very well considered Japanese made switches, these are from the mid 1990's M8 series NOT the MX type used in professional/consumer and gaming keyboards.
These switches are extremely difficult to find, I am offering these for those who need to restore a failed switch in older Japanese keypads - usually found in Japanese test equipment, data entry keypads and some musical equipment of the day.
Hirose switch
Brand: Cherry
M8 series
Mount: 4x PCB pins plus two locating plastic pins
Body colour: Black
Body material: plastic
Stamped identification on the switch body top
HIROSE
CHERRY
On the underside of the switch is stamped a diode symbol, indicating the LED polarity.
Electrical function: Push On Release Off
Chip LED sits inside the plunger and is totally isolated from the switch function
LED emission colour is 1x Red & 2x Green PLEASE SPECIFY WHICH LED COLOUR IS REQUIRED (I only have those indicated here)
Tactile "feel": very smooth plunger operation
Complete sealed - no internal access unless you wish to destroy the switch!
Top fitting: this is NOT the cross style fitting but a slot. Normal keyboard caps will not fit this switch properly.
I do have a number of suitable top caps, removed from the test equipment I have recently "parted out" - there is a separate advertisement for these top caps.
Mounts direct onto the PCB, 4x holes for the electrical connections and two holes for the locating pins.
Switch body dimensions: 13mm x 14mm x 8mm height (off the PCB)
Switch plunger: 5mm normal 3mm fully pushed down
Carefully removed from the original test equipment keypad PCB - NO pins are damaged, excess solder cleaned off! NO heat damage to the switch
To be quite sure, I have tested each and every switch
Extremely high open resistance and very, very low "ON" resistance
LED (all switches, both green and red) tested at 2.5V forward voltage - all good.
Supplied sealed in plastic
