Product details

Safety interlock with trapped-key logic

The Omron A22TK-2RR-03-02 is a trapped-key safety selector switch designed to prevent operators from being trapped inside hazardous areas during maintenance. The key is released only when the switch is in the right-hand position, and the normally-closed contacts (TPST-NC) open in that same position, breaking the safety circuit. This mechanical interlock ensures the machine cannot re-energize while the key is removed and the guard is open. The 22 mm diameter round panel cutout matches the standard A22 mounting hole, and the IP65 enclosure rating means the switch body withstands washdown and dust ingress — suitable for food processing, pharmaceutical, or general wet-area guarding applications.

Frequently asked questions

What is the A22TK-2RR-03-02 used for?

It is a safety key selector switch that prevents operators from being trapped inside hazardous areas during maintenance. The key is trapped in the switch until the contacts open, ensuring the machine is isolated before the guard can be opened.

Where can I buy the A22TK-2RR-03-02?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at the time of quote.

What is the panel cutout size for this switch?

The switch requires a 22 mm diameter round panel cutout, which is the standard A22 mounting size.

What is the contact configuration?

The contact form is TPST-NC (triple-pole single-throw, normally closed). All three NC contacts open when the key is in the right-hand release position.
