Claims

[Scope of utility model registration request]

In a keyboard switch in which contact patterns are separately formed to form a required set of switches on each opposing surface of two insulating sheets arranged oppositely at a required interval, the switch operation area according to the corresponding contact pattern is A pseudo spacer is provided on one or both of the insulating sheets to cover wiring patterns other than those connected to the contact pattern. keyboard switch.
