Machine designers and panel builders like to have a variety of choice for both bezel materials and colour options when choosing pushbuttons for their equipment. The new compact A22N series certainly delivers on this requirement, as well as being more compact and simpler to install. The A22N series includes 22-mm diameter push buttons, knob-type selector switches, key selector switches, and indicators.
Short compact body
The A22N range is 30% shorter in the body compared to previous models, only 45.3mm when mounting three contact blocks in a series (for non-lighted models). This can contribute to panel downsizing in regards to depth as the pushbuttons will no longer interfere with other product mounted inside the panel.
New design innovations make installation easier, such as the snap-in switch unit, which makes tool-free assembly both quick and easy. Additionally, up to 6 contact blocks can be mounted in two rows and the symmetrical contact block design allows them to be mounted in either orientation.
You can also re-tighten the contact blocks in row one without removing row two and the enhanced IP66 finger protection rating provides greater operator safety.
Enhanced aesthetics to suit any need
It is also possible to expand and customize standard A22N switches by adding extra switch units. The bezel materials available for the A22N range are black plastic, brushed metal and polished metal and a full range of popular colours are available:
- Non-lighted pushbuttons and selector switches: red, green, yellow, white, blue, and orange with both opaque and transparent options and black opaque
- Lighted push buttons, selector switches and indicators: red, green, yellow, white, blue, and orange
