REES

REES is a manufacturer of industrial push-button switches and emergency-stop devices, with a product line centered on mushroom-head push buttons. The brand is known for producing non-illuminated, non-metallic mushroom-head push buttons in standard panel-mount diameters of 22 mm, 30 mm, and 57 mm. These components are used in machinery control stations, safety circuits, and industrial automation systems where a robust, manually operated stop or start function is required. REES push buttons are typically offered with maintained or momentary action, and contact configurations include 1NO/1NC, 2NC, and single-pole variants. The non-metallic construction of the actuator and housing provides electrical insulation and resistance to corrosion in industrial environments. Terminal connections are commonly pressure-plate type, facilitating secure wiring without specialized tools. 3G Electric supplies a range of REES mushroom-head push buttons, including emergency-stop models with red mushroom-head profiles. The product range covers multiple panel cutout sizes and contact arrangements, allowing engineers to select the appropriate switch for their control panel design. All REES push buttons listed by 3G Electric are non-illuminated, making them suitable for applications where visual indication is not required or where ambient lighting is sufficient. The maintained-action variants latch in the pressed position, requiring a twist-to-release or pull-to-release mechanism to reset, which is a standard safety feature for emergency-stop devices. Momentary-action variants return to the normal state when released, suitable for start or jog functions. 3G Electric supports procurement by providing detailed specifications for each SKU, including manufacturer part numbers, action type, material type, and terminal connection method. This enables buyers to match the exact replacement or new-installation requirements without ambiguity. The availability of multiple SKUs across different diameters and contact configurations ensures that REES push buttons can be integrated into both new control panels and retrofit applications. For plant engineers and maintenance managers, the non-metallic construction reduces the risk of accidental grounding and simplifies compliance with electrical safety standards. Procurement specialists can source REES push buttons through 3G Electric with confidence in the consistency of the product line across different part numbers.

Frequently asked questions

Common questions about REES from 3G Electric.

What are the available panel cutout diameters for REES mushroom-head push buttons?

REES mushroom-head push buttons are available in three standard panel cutout diameters: 22 mm, 30 mm, and 57 mm. The 22 mm and 30 mm sizes are common for control panels and operator stations, while the 57 mm diameter is typically used for larger emergency-stop actuators that require a more prominent profile for quick access. Each diameter corresponds to specific manufacturer part numbers, such as the 22102 series for 22 mm and the 40102 series for 30 mm.

Are REES emergency-stop push buttons maintained or momentary action?

REES emergency-stop push buttons are available in both maintained and momentary action types. The maintained-action models, such as MPN 40102-212, latch in the pressed position and require a manual reset (twist or pull) to release. Momentary-action models, such as MPN 02182-002, return to the normal state when released. The action type is specified in the product specifications, allowing selection based on safety circuit requirements.

What contact configurations are offered for REES push buttons?

REES push buttons are offered with various contact configurations, including 1NO/1NC (one normally open and one normally closed contact), 2NC (two normally closed contacts), and single-pole configurations. For example, the 57 mm model MPN 04956-102 has 1NO/1NC contacts, while the 22 mm model MPN 22102-312 has 2NC contacts. The contact arrangement is specified in the manufacturer part number and product summary.

What is the material construction of REES push buttons?

REES push buttons are constructed with non-metallic materials for both the actuator (mushroom head) and the housing. This non-metallic construction provides electrical insulation, reduces the risk of accidental grounding, and offers resistance to corrosion in industrial environments. The material type is listed as 'Non-Metallic' in the product specifications for all REES SKUs supplied by 3G Electric.

How are REES push buttons terminated?

REES push buttons use pressure-plate terminal connections for wiring. This type of terminal allows secure clamping of wires without the need for specialized tools or crimp connectors. The pressure-plate design is standard across the REES product line, as seen in models like MPN 02182-002. This simplifies installation and maintenance for panel builders and technicians.
