Sylvania Joslyn Clark 100T CB11 Pushbutton Contact Block

The Sylvania Joslyn Clark 100T-CB11 Pushbutton Contact Block is a dual-contact accessory that mounts under a 100T-series pushbutton, providing both a normally open and a normally closed contact in one compact block. It comprises two sub-blocks—100T-CB10 (1-N.O., green) and 100T-CB01 (1-N.C., red)—packaged together as the CB11 assembly for use in control circuits. Rated for up to 10 A at 600 V AC, it is designed for industrial switching applications and is compatible with standard 100T pushbuttons. In panel installations, the NO portion is color-coded green and the NC portion red, allowing immediate visual indication of the contact state; this arrangement enables simultaneous primary circuit control and auxiliary feedback or interlock signaling with a single pushbutton. Common applications include motor-control interlocks, start/stop arrangements, and safety-related control circuits where a single pushbutton must drive two complementary contacts.
