FAQ

SH-B2 22mm Push Button Switch Frequently Asked Questions

How do I select the correct SH-B2 22mm push button switch?
Start with the panel cutout, operator action, contact mix, and lamp voltage. SH-B2 uses a 22 mm panel hole, Ui 440V insulation rating, 10A thermal current, and BA contact blocks such as 1NO, 1NC, 2NO, or 2NC. For a quote, send the function list, color, marking, contact configuration, voltage, quantity, certification market, and delivery schedule.
What is the difference between flat, illuminated, selector, and emergency-stop SH-B2 operators?
Flat heads suit start, stop, reset, and jog commands. Illuminated heads add an LED lamp for run, fault, or power status. Selector and key switches handle manual/auto mode or access control. For emergency-stop positions, use BS-series mushroom operators with latching release and verify the machine safety requirement before approval.
Which standard applies to SH-B2 contact blocks and control-circuit use?
SH-B2 contact blocks are specified around IEC/EN 60947-5-1 control-circuit device requirements and GB/T 14048.5. The practical selection point is whether the contact rating matches the control load, such as AC-15 contactor coils or DC-13 relay circuits. For standards context, see the IEC standards reference.
What IP rating should I expect from SH-B2 push buttons?
The standard SH-B2 page-front specification is IP40 with IP20 terminals, which is suitable for enclosed control cabinets and dry indoor panels. If the operator surface is exposed to oil mist, dust, outdoor moisture, or wash-down, confirm the enclosure plan first and consider a higher-seal option such as SH-GQ IP65 metal operators.
What certifications and documents should be confirmed before ordering?
Confirm CE, CCC, and RoHS status for the order destination, then ask for the catalog page, wiring reference, and packing details. For export projects, include the required certification market and any customer drawing numbers in the inquiry. Shieldhz can prepare the documentation package together with the selected operator and contact-block list.
Where is SH-B2 normally used in industrial panels?
Typical uses include machine-tool start/stop stations, conveyor control boxes, compressor and pump panels, HVAC equipment, and OEM machinery cabinets. Use SH-B2 for modular 22 mm plastic operators with many head types. If the panel also needs status-only indication, compare the AD16 panel indicator light page.
Can Shieldhz support custom markings, colors, or OEM push button assemblies?
Yes. Standard red, green, yellow, blue, white, and black heads are available, and custom legend plates or symbol markings can be prepared for OEM quantities. For mixed operator interfaces, compare the parent Shieldhz push buttons and indicator lights page and send the bill of materials through the quote form below.
