Zinc-alloy bezel metal push buttons in three panel cutout sizes. Flat heads, ring-lamp illuminated, annular indicator lamps, and emergency-stop variants — all CE and CCC certified for industrial control panels.
SH-GQ metal push buttons are available in 16 mm, 19 mm, and 22 mm cutout sizes. Each size covers flat, illuminated, indicator, and emergency-stop variants with zinc-alloy bezel construction.
Compact 16 mm cutout for space-constrained panels. Flat head, high-head ring lamp, annular indicator lamp, power supply marker, and small-head emergency stop. Zinc-alloy bezel with IP65 sealing.
Mid-size 19 mm format balancing ergonomics and panel density. Available with ring lamp, annular lamp combined with power-supply indicator, and small-head emergency stop. Common in HVAC and building automation panels.
Industry-standard 22 mm cutout for direct compatibility with standard DIN-rail enclosure door knock-outs. Flat head, ring lamp illuminated, annular indicator lamp, and small-head emergency stop variants.
Seven product types in the 16 mm format: flat operators, illuminated ring-lamp heads, annular indicator lamps, power-supply markers, and compact emergency-stop buttons.
Mid-size 19 mm cutout format with flat, illuminated, combined indicator, and emergency-stop types. Bridges compact 16 mm and standard 22 mm panel designs.
Standard 22 mm cutout — the most common industrial panel size. Compatible with standard DIN-rail enclosure knockouts. Flat, ring-lamp, annular indicator, and e-stop variants.
Applies to all SH-GQ push button and indicator lamp types unless noted. Specifications consistent across 16 mm, 19 mm, and 22 mm sizes.

MCC and switchgear panel doors. Metal bezels resist vibration and mechanical abuse from frequent use. Ring-lamp variants confirm relay and contactor status without opening the door.
Lathes, milling centres, and press-brake operator stations. Metal bezel withstands cutting fluid splash and swarf impact. IP65 sealing prevents ingress during coolant wash-down.
Pendant stations and floor control posts for overhead cranes and hoists. Metal construction survives daily impacts. GQ16 compact format suits pendant enclosures; e-stop for safety circuits.
Fan start/stop, pump control, and lighting selector panels in commercial buildings. GQ19 mid-size format common in HVAC control boxes. Power-supply marker lamp shows supply status at a glance.
Annular lamp variants serve purely as status indicators — no switch function. Mix with push buttons in the same cutout size for a uniform panel aesthetic. Available in red, green, yellow, white, blue.
Standard 16/19/22 mm cutouts are universal — GQ series drops into existing panel holes. Metal bezels match stainless steel enclosure aesthetics for food-processing and pharmaceutical OEMs.
Send the panel cutout size, operator type, contact configuration, lamp voltage, bezel material, color, marking, quantity, certification market, and delivery schedule. For replacement projects, verify panel depth, gasket seating, terminal clearance, and wiring before approving a substitution.
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.
