Push Button Switches
ALX-HB4-BL83 Double Head Push Button Switch | 22mm 1NO+1NC
22 mm double head push button switch: two caps in one 22 mm body, 1 NO plus 1 NC contact, momentary action, red/green or green/red cap order, zinc alloy chrome bezel, screw terminals, 600 V AC 10 A.
The HB4-BL83 packs a start and a stop function into a single 22 mm hole: two caps sit side by side in one bezel, one wired normally-open and one normally-closed. On a panel with limited space that halves the number of holes and keeps the pair of commands where the operator expects them, next to each other.

Design Features
- Two actuators in one 22 mm cutout, which halves the panel drilling compared with separate start and stop buttons
- One normally-open and one normally-closed contact in the same body, so a start/stop pair needs a single wiring point
- Caps are mechanically independent: pressing one does not move the other
- Chrome-plated zinc alloy bezel with metal clamping ring, sized to the standard 22 mm hole
- Contact blocks clip on separately, so either side can be replaced without removing the bezel
