22mm 3Amp Self-Reset 3 Position Plastic Key Switch

Description

The 22 mm self-reset 3-pole rotary switch with key is a compact, panel-mount selector switch designed for controlling power or operational modes in equipment. It mounts through a standard 22 mm hole and uses a keyed rotary knob — meaning the switch can only be operated by inserting and turning the key, which helps prevent accidental or unauthorized activation.

The “3-pole” configuration allows it to control multiple circuits simultaneously, making it suited for more complex switching needs than a simple on/off switch. Its self-reset (or self-return) mechanism returns the knob to its default (neutral) position automatically when the key is released, providing momentary control — convenient for functions like “start/stop,” “momentary ON,” or “cycle through modes” rather than permanent latching. With a sturdy metal (or plastic-reinforced) body and push-button/knob-style interface, the switch is commonly used in industrial control panels, automation systems, machinery controls, or any equipment requiring secure, key-controlled momentary switching.
