Relay Specialties, Inc. - Omron - Products - Switches - Pushbutton Switches/Indicators - φ22(φ25) Type

Improved wiring visibility through to a modified wiring direction. (Push-In Plus terminal block type)
Screw terminal structure is compatible with round crimp terminals. (Screw terminal block type)
The terminals can be secured even when a contact block is mounted. (Screw terminal block type)
No need for extra lateral space because of the modified wiring direction. (Push-In Plus terminal block type)
Compact design.
A22NW (lighted models) are the same size as A22NS (non-lighted models).
Easy-to-operate lock lever for secure locking.
Easy-mounting Contact Blocks provide finger protection.
No loose connections of wiring means maintenance-free use. (Push-In Plus terminal block type)
Meets global safety standards.
Can be installed in two types of panel hole dimensions: 22.3 and 25.5 dia.
The buttons and bezels come in a wide variety of colors, shapes, and materials.
Standard-feature degree of protection: IP66, NEMA 4X, and NEMA 13.
