High quality EAO (Switzerland) panel switches extracted from some vintage broadcast audio panels ... there are a few different types, please read the description below.
EAO - Panel Switch With LED Indicator
Made in Switzerland
SWITCH 1
TYPE: 98-323
PCB through hole terminals
2x diagonal locating plastic pins to help secure and orientate the switch when installed on a PCB
Single 3mm LED installed (RED) - this LED can easily be changed to a different colour if required.
Electrical action: SPDT
Physical action: Nice positive 'click' action when depressed
These switches were well known for their long term reliability, an absolute must in the broadcast industry - typically these switches are rated for 5 million operations MTBF. If the panel operator is pushing this switch in excess of 5 million operations, human therapy is probably required!
The switch front has a small window into which can be inserted a user provided function label, a clear plastic 'clip on' cover snap fits over this window.
DIMENSIONS:
Black front button: 17.38mm x 17.32mm
Light Grey rear switch: 7.25mm H x 14.5mm x 11mm
Tested the switch for both the physical action and electrically, no issues at all
I have not tested the LED but have no doubt it is fine and in any case, it can easily be "swapped out" for another LED of the same or another colour.
SWITCH 2
TYPE: 98-323
PCB through hole terminals
Identical to SWITCH 1 (above) but without the LED fitted
Electrical action: SPDT
Physical action: Nice positive 'click' action when depressed
These switches were well known for their long term reliability, an absolute must in the broadcast industry - typically these switches are rated for 5 million operations MTBF. If the panel operator is pushing this switch in excess of 5 million operations, human therapy is probably required!
The switch front has a small window into which can be inserted a user provided function label, a clear plastic 'clip on' cover snap fits over this window.
Tested the switch for both the physical action and electrically, no issues at all
SWITCH 3
TYPE: Unknown
I am not convinced that this switch is an EAO product, although very similar in appearance, there are no markings on the body of this switch at all.
PCB through hole terminals
2x diagonal locating plastic pins to help secure and orientate the switch when installed on a PCB
Double 3mm LED's installed (RED) - these LED's can easily be changed to a different colour if required.
Electrical action: SPDT
Physical action: Nice positive 'click' action when depressed
The switch front has a clear plastic 'clip on' window cover into which can be inserted a user provided function label.
DIMENSIONS:
All Black button (front button and rear switch): 17.35mm x 17.35mm x 11.45mm H
Tested the switch for both the physical action and electrically, no issues at all
I have not tested the LED's but have no doubt these are fine and in any case, they can easily be "swapped out" for other LED's of the same or another colour.
