Push Button Switches
ALX-HB4-BA11 Flush Metal Push Button Switch | 22mm 1NO
22 mm flush metal push button switch, 1 NO contact, momentary action, five cap colours (white, black, green, yellow, blue), zinc alloy chrome bezel, screw terminals, 600 V AC 10 A.
The HB4-BA11 group is the normally-open flush button of the HB4 range, supplied in five cap colours so a panel can colour-code its start, reset and jog functions without changing hardware. It uses the same chrome-plated zinc alloy bezel and 22 mm cutout as the rest of the family, and the contact block is a standard screw-terminal block that can be exchanged from the front of the panel.

Design Features
- Five cap colours from stock: white, black, green, yellow and blue caps share the same bezel and contact block
- One normally-open contact block, screw terminals, marked 600 V AC 10 A for AC-15 duty
- Coloured cap is a separate moulding, so a cap can be swapped to re-colour a panel without changing the wiring
- Flush profile: the cap does not protrude past the bezel ring, which keeps the panel face flat for wipe-down and guarding
- Zinc alloy bezel, chrome plated, resists knocks from tools and workpieces at the panel edge
