ET
RoHS Compliant
■ Introduction
The ET series is Copalʼs standard size high capacity
toggle switch. The ET series are available in various
current rating, switching functions, and terminals.
The housing is made of self-extinguishing phenol
resin which has excellent heat resistance, arc
resistance, and tracking resistance. The contacts are
designed to eliminate chattering and bouncing to
prevent insulation deterioration.
