Push Buttons

820 & 821

The Catalog 820 and 821 are rugged, fast break contact push but-

tons that operate regardless of how pressure is released. The Cata-

log 821 is ideal for mounting on thin metal panels.

Ideal for AC circuits where quick make is not a factor. The 821 may

be used with 149-1 mounting plate. See page 10-11.
