Abstract:

A switch construction, particularly a rapid data entry switch for connecting one or more select contact circuits comprises a first block member which has a first finger engagement side and an opposite second side which is arranged in opposition to a second block member first side. The second block member defines one or a plurality of contact guide bores therethrough and it provides a pivotal support base for the first block member. The first block member advantageously has recesses defining finger engagement positions which when depressed by a finger engagement will cause the first block member to pivot on the second block member to displace a select contact rod member in order to cause it to actuate or establish a connection in a select contact circuit. The block member is comprised of rectangular block elements having opposed surfaces which are formed as pyramidal segments which interengage.
