Control pushbutton enclosure Rittal HD 1682.630 stainless steel, 2 pushbuttons, 30.5 mm

Rittal HD 1682.630 is a stainless steel control pushbutton enclosure designed to house two 30.5 mm pushbuttons. Constructed from stainless steel (material 1.4301) and intended for panel mounting, the enclosure provides a compact, corrosion-resistant shell with precision cut-outs for switches. The design includes an all-round gap-free silicone seal between enclosure and cover and a hygiene-compliant quick-release hexagon fastener, making it suitable for environments with strict cleanliness requirements such as the food and beverage industry.

Advantages

The stainless steel construction offers durable resistance to corrosion and mechanical wear while maintaining a hygienic surface that is easy to clean. The gap-free silicone seal prevents ingress of liquids and particulates at the enclosure-cover interface, and the quick-release hexagon fastener enables rapid access for maintenance without compromising seal integrity. The compact format and precise 30.5 mm cut-outs ensure secure mounting of two standard-size pushbuttons and stable operation of control elements.

Suitable for

• Control panels in food and beverage production where hygiene and washdown resistance are required
• Industrial machinery control stations that need compact, corrosion-resistant enclosures
• Process control and automation applications with two pushbutton inputs
• Panel-mounted operator interfaces in wet or humid environments

When it may not be suitable

This enclosure is tailored for two 30.5 mm pushbuttons; it is not suitable for devices of different diameters or for applications requiring more switch positions without using adapters or custom modifications. It is also not intended as a housing for components requiring additional internal mounting features, extensive wiring space, or integrated electronics unless additional internal supports are added.

Key specifications

• Material: Stainless steel (1.4301)
• Pushbutton cut-outs: Two × 30.5 mm diameter
• Mounting: Panel-mounted enclosure
• Seal: All-round gap-free silicone seal between enclosure and cover
• Fastening: Hygiene-compliant quick-release hexagon fastener
• Application focus: Designed for hygiene-critical environments (food and beverage)

How to use

Prepare the control panel by cutting and deburring the panel apertures according to the enclosure's mounting dimensions. Install the enclosure into the panel cut-out and secure it using the quick-release hexagon fastener, ensuring the silicone seal seats evenly around the cover to maintain a gap-free seal. Fit two compatible 30.5 mm pushbuttons into the provided cut-outs and complete internal wiring following applicable electrical standards and safety regulations. For maintenance, release the hexagon fastener to open the cover, perform required servicing, then reseat the seal and resecure the fastener to restore protection.

What to consider before purchase

• Verify that your pushbuttons are 30.5 mm in diameter and compatible with panel-mounted housings
• Confirm panel cut-out dimensions and available depth behind the panel for internal wiring and components
• Assess whether the enclosure's stainless steel grade (1.4301) meets your corrosion resistance requirements
• Determine if additional internal mounting or cable gland provisions are required for your installation

Usage recommendations

Use Rittal HD 1682.630 in hygiene-sensitive production areas; clean surfaces with compatible detergents, avoid abrasive tools that could damage the seal, and follow machine-maker guidelines for electrical connections to maintain both operational safety and ingress protection.
