Product Introduction

This switch presents a sealed rocker, membrane key or touch surface within a stainless cleanroom plate. The broad flange closes the wall opening and the rear box contains terminals away from the room cavity. Laser-etched function labels and a small status indicator can be incorporated without applied paper labels or projecting pilot devices.

Key Features

A membrane or gasketed rocker prevents an open slot around the moving control.

The flush plate aligns with modular wall panels for direct wiping.

Permanent engraving identifies the controlled lighting zone.

An optional indicator shows circuit state without a separate wall penetration.

The enclosed rear mechanism protects terminal screws from cleaning moisture.

Customer Product Concerns

A wall switch is touched frequently and must remain readable, sealed and operable with cleanroom gloves.

Narrow rocker gaps accumulate skin oils and disinfectant.A continuous membrane or sealed actuator removes the open perimeter slot.

Printed adhesive labels peel after chemical cleaning.Laser engraving provides permanent circuit identification.

Small switches are difficult to operate through gloves.A broad tactile actuator provides a clear positive response.

Cleaning fluid reaches exposed rear terminals.A sealed rear box and gland enclose the wiring connection.
