Shieldhz supplies industrial control components for panel builders, machinery OEMs, solar PV systems, and building equipment. Explore rotary cam switches, DC isolators, push buttons, indicator lights, and waterproof isolator boxes by product family and series.
Start with the product family that matches your circuit, panel, or installation environment. Each category page includes series routes, ratings, mounting options, drawings, and quotation notes.
Selector, changeover, meter selection, motor-control, and multi-position switching for industrial panels and equipment.
View Rotary Cam Switches
DC disconnect switches for solar strings, combiner boxes, inverter inputs, and maintenance isolation in PV systems.
View DC Isolators
Start, stop, selector, emergency-stop, pilot-light, buzzer, and status indication devices for cabinet doors and machine panels.
View Push Buttons
Pre-enclosed local isolation for pumps, HVAC units, outdoor machinery, wash-down areas, and field disconnect points.
View Isolator BoxesStart from the panel, machine, PV system, or outdoor equipment when the exact product family is not yet clear.
Panel-mounted switches, push buttons, pilot lights, and manual switching for cabinets and switchboards.
Selector switches, emergency stops, status lights, and isolators for machine builders.
DC isolators for strings, combiner boxes, inverter inputs, and solar service points.
Weatherproof isolator boxes for pumps, fans, outdoor machinery, and wash-down areas.
Start, stop, selector, E-stop, and indication devices for machine operation panels.
Local isolation and enclosed switching near service equipment, fans, pumps, and HVAC units.
Use this compact index when the buyer already knows a Shieldhz series name and needs to move directly into model-level data.
Keep this section scan-first: series code, application fit, and the next page. Detailed ratings stay on the series pages.
Start from the circuit role, then confirm the data that controls model coding: ratings, mounting, configuration, and certificate requirements.
Match the component to the work it performs before narrowing the series and final model code.
Manual selection, changeover, meter, motor, and multi-position switching in control panels.
Solar string, combiner box, rooftop, and inverter-side disconnection for DC circuits.
Start, stop, reset, emergency, and status indication on machine or cabinet panels.
Local isolation for pumps, HVAC, machinery, and exposed service points.
What does the component control, signal, or isolate?
Which electrical and environmental limits apply?
Which series, mounting, certificate, quantity, lead time, and documentation package should be quoted?
For industrial control components, trust should be visible: real production, documented certificates, and model selection support before quotation.
Workshop processes cover component assembly, production equipment, packing flow, and inspection points for repeatable supply.
Certificate files are checked by series, rating, and market, so a quote can reference the document that actually applies to the selected model.
Selection support covers AC/DC duty, pole count, contact program, IP rating, cable entry, mounting style, and enclosure requirements.
Application photos, drawings, wiring logic, and electrical data can be reviewed before final model coding and quotation.
Certification availability varies by product family, series, rating, and destination market. Use the Resource Center certificates as document references during model confirmation. For standards context, compare the request with the UL Standards Catalog or the IEC document named by the buyer, then confirm the exact certificate, documentation package, MOQ, and lead time for the selected model.
Start with the application role. Use rotary cam switches for manual switching logic, PV DC isolators for solar DC circuits, push buttons and indicators for operator panels, and waterproof isolator boxes for outdoor disconnect points.
Send voltage, current, AC or DC duty, poles, contact program, mounting method, enclosure or IP requirement, quantity, destination market, required certificate, lead time target, and documentation package. A product photo, panel cutout size, or wiring diagram helps with replacement projects.
Yes. A control cabinet may combine rotary cam switches, push buttons, pilot lights, and terminal wiring. Solar or outdoor equipment projects may combine DC isolators with enclosed isolation points.
Use the family page first, then move into the series index for model-level selection. The final series depends on rating, mounting, pole count, enclosure route, and the required certificate path.
Certificate availability is confirmed by product family, series, rating, and destination market. Use the Resource Center documents as references, then confirm the exact certificate needed for the selected model.
Rotary cam switch programs, handle markings, pole counts, enclosures, cable entries, and some operator panel combinations can be reviewed against the application before sampling or quotation.
Yes. Send front and side photos, existing markings, wiring information, panel hole size, and the equipment environment. Shieldhz can then suggest the nearest category, series, and configuration route.
Share the application, voltage, current, mounting method, protection rating, quantity, target market, required certificate, MOQ target, and delivery schedule. Shieldhz will confirm the suitable product family, series, lead time, and documentation package before quotation.
