22 mm modular push buttons, metal push button switches, selector switches, emergency stops, and LED panel indicator lights for machine tools, control cabinets, automation lines, and building systems.
Start with the operator-interface function. SH-B2 covers standard 22 mm modular push buttons, SH-GQ adds 16 / 19 / 22 mm metal-front options, and AD16 provides dedicated LED pilot-light status indication.
Standard modular push buttons for machine tools, MCC panels, conveyors, and OEM replacement. SH-B2 / LA28 / LA38 22 mm catalog variants cover flat buttons, illuminated buttons, selectors, key switches, double buttons, and emergency stops.
Chrome and metal-front push buttons for durable equipment interfaces. Choose flat heads, ring-lamp buttons, annular indicators, power marker lamps, and compact emergency-stop options.
Dedicated pilot lights for power, run, fault, alarm, and PLC output status. Available in standard, flat, double-hole, and buzzer indicator variants for control-panel indication.
Push button factory video
This short video supports push button and indicator light sourcing by showing factory production, automatic packaging, quality control, and supply capability for industrial electrical projects.
Use this comparison to route operator inputs and status outputs in one matched panel set. Before quoting, confirm Ui 440V, Ith 10A, 2,000,000+ mechanical operations, 500,000+ electrical operations, AD16 50-60Hz / ≤20mA lamp requirements, and SH-GQ 1.8V-380V body-material options.
| Product line | Main function | Cutout | Front style | Protection | Typical use | Best choice when |
|---|---|---|---|---|---|---|
| SH-B2 22 mm push buttons | Operator input: start, stop, reset, jog, mode selection, emergency stop | 22 mm | Modular plastic head with contact block assembly | IP40 / IP65 options | Machine tools, MCC doors, conveyor stations, OEM replacement panels | You need a cost-effective standard 22 mm push button family. |
| SH-GQ metal push buttons | Operator input and metal-front indication with ring-lamp options | 16 / 19 / 22 mm | Chrome or metal bezel, flat and illuminated styles | IP65 front options | CNC panels, HVAC boxes, equipment consoles, crane controls, retrofit builds | You need a stronger front appearance or compact metal button sizes. |
| AD16 panel indicator lights | Status output: power, run, fault, alarm, PLC signal, audible warning | 16 / 22 mm | LED pilot light, flat light, double-hole light, buzzer indicator | IP40 / IP65 options | Power distribution boards, PLC panels, alarm panels, HVAC status panels | You need visual or audible status display rather than a control input. |
The same control panel often uses more than one family: push buttons for commands, selectors for modes, emergency stops for shutdown, and AD16 lights for status feedback.
Compact operator stations for start, stop, reset, direction, and local control along automated production lines.
Power, run, trip, high-level, fault, and audible warning signals for PLC panels and process equipment.
Map the operator interface before model coding: use SH-B2 or SH-GQ for command inputs, selector and key functions for mode control, emergency stops for shutdown, and AD16 lights for status feedback.
Green start, red stop, black reset, and jog buttons for direct operator input.
Manual/auto, local/remote, fan/pump selection, or authorized access through selector and key-operated heads.
Mushroom-head stop buttons for safety shutdown positions on machines, operator panels, and pendant stations.
AD16 pilot lights and buzzer indicators show power, run, trip, alarm, and PLC output states without opening the panel.
A clear push button inquiry should include mechanical installation details, electrical contact or lamp requirements, target market, MOQ, lead time, and the documentation package needed for incoming inspection.
Practical rule: choose SH-B2 when the panel uses standard 22 mm modular controls, SH-GQ when the front face needs a metal button appearance, and AD16 when the function is visual or audible status indication rather than a switching input. For projects that specify industrial control devices, confirm the buyer’s required standard route, such as IEC 60947-5-1, before the final model list is approved.
Manufacturer support: Zhejiang Shihe Electric Co., Ltd. was founded in 2014 and runs ISO 9001 production management from a 5,000+ sqm factory. Shieldhz can support CE, TUV, UL, UKCA, CCC, RoHS, or CB documentation where the selected product variant and market require it.
Send cutout size, function list, voltage, colors, contact configuration, quantity, certification market, and delivery schedule. Shieldhz will match SH-B2, SH-GQ, and AD16 into one control-panel bill of materials.
