Clare-Pendar S830 is a series of tall, cylindrical-body reed switches made by Clare-Pendar.
Description
No written details of S830 are currently known to have survived. Switches found to date—including those sold by STRONIC in France—have an open-top cylindrical slider, into which adapters are fitted to provide a keycap mount of the customer's choice. There is a suggestion in the wording of the E9 modification that some switches were used without an adapter but the specifics of this are not clear.
The switches are screw mount, affixing to the PCB with a bolt. The switches found so far have Clare-Pendar moulded into the shell.
Known modifications
The following modification codes have been found. It is not clear whether they all apply directly to S830 series part numbers, as the S830 catalogue page itself is lost.
