HQ 22mm Controls: Push Buttons and Indicator Lights

Published October 17, 2023 Source Wenzhou Jinhong Electric 2 min read

Plan a panel with HQ push buttons and indicator lights. Compare operating heads, contact functions, lamp supplies and installation space.

In this article

Jinhong’s HQ range includes 22mm push buttons and indicator lights. It gives panel builders several ways to present commands and equipment status within a coordinated control layout.

Match the head to the task.

The push-button catalogue includes standard, extended and mushroom-style heads. Select an operating surface that suits access and use. A larger mushroom head alone does not make a device an emergency stop; that function requires the appropriate dedicated device and system design.

Specify contacts and illumination.

Check whether the selected model is momentary or latching and identify the circuits it must switch. For illuminated controls, specify the lamp supply separately from the contact rating. A button used to signal a PLC input has different load requirements from one used to switch a relay coil.

Review the complete installation.

Use the model drawing for the mounting hole, panel thickness and rear depth. Leave space for contact blocks, conductors and service access. Confirm that each accessory belongs to the chosen HQ assembly rather than assuming that parts from another 22mm family are interchangeable.

The HQ push-button catalogue and HQ indicator catalogue provide the starting points for a panel bill of materials.

HQ panel bill-of-materials checks

Order the complete assembly rather than describing only the visible head. Keep the required contact and lamp details with each control position.
