Short depth behind the panel for compact equipment.

Double: 59.9mm (maintained: 64.6mm) Single: 39.9mm (maintained: 44.6mm)

Switching capacity is 120V AC, 10A (resistive load). The compact style requires less depth behind the panel.
Can be used with IDEC's FB and other 22mm control boxes. No transformer needed for any voltage.

Sleek and stylish switches and pilot lights
with a 2.5mm-thick bezel

The CW series gives a sleek, stylish image to your machines or con­trol panels. The surface is safer with less chance of unexpected opera­tion or accidents by hitting the projections, and also is cleaner with
less dust build-up.

Safety

Third-generation
safety construction

Two-action removal of contact blocks

IDEC’s original two-action push-turn locking lever provides a higher
level of safety by preventing unexpected release of the locking lever.
Whether the contact block is installed securely can be checked easily
from the back of the panel, with the position of the locking lever.

Locking lever integrated
with guard

Prevents locking lever from un­expected release or damage by
trapped wires.
