30mm Key Switches for Industrial Compactor Control Panels
30mm key-operated switches for industrial trash compactor control panels. 2-position and 3-position operator-authorization switches that restrict cycle starts to trained operators. Drop-in compatible with the 30mm panel cutouts used on most pre-2015 industrial compactors.
What this page covers
Key switches authorize compactor operation — the cycle won't start unless a trained operator inserts a key and turns it to the active position. The result is a clear chain of custody for compactor use, plus reduced risk of unauthorized cycling that creates safety incidents.
PRT stocks 30mm key switches in 2-position (off/on) and 3-position (off/manual/auto) configurations, with standard key codes for keyed-alike installations or unique codes for high-security routes.
How to choose
Match by position count (2 or 3), key code (standard or custom), and contact block configuration (1-NO, 1-NC, 1-NO/1-NC).
For fleet operations, specify keyed-alike when ordering. Managing dozens of unique keys across multiple compactors becomes an operational problem.
In stock options
- 2-position 30mm key switch Off / on — the most common configuration.
- 3-position 30mm key switch Off / manual / auto — for compactors with mode selection.
- Standard key code Common keyed-alike default.
- Custom key code Unique codes for security-sensitive installations.
- Replacement keys When original keys are lost or copied.
- Contact blocks Snap-in 1-NO, 1-NC, or 1-NO/1-NC blocks.
Frequently asked questions
What's the difference between a 2-position and 3-position 30mm key switch?
2-position is off/on — the simplest operator-authorization switch. 3-position adds a third option, typically off/manual/auto for compactors that can run in either mode.
Can I get keyed-alike key switches for my entire compactor fleet?
Yes. Specify keyed-alike when ordering and all switches will operate on the same key. Useful for multi-site operations.
Are PRT 30mm key switches compatible with Marathon and PTR compactor panels?
Yes. The 30mm panel cutout is an industry standard — PRT key switches fit any panel cut for 30mm hardware.
How do I order replacement keys for an existing 30mm key switch?
Provide the key code stamped on the existing key. Without a code, replacement requires the full switch.
