ROFU 9200 Series SPDT Key Switches, Narrow Stile, 10A/250V-15A/125V

Momentary is the one you want for a normal release: turn the key, the contact transfers, then it springs back and the door relocks. Maintained holds its position until you turn the key back, so it is the choice for putting an opening into a sustained unlocked or bypass state, like holding a door free during business hours. The ROFU 9200 Series is offered both ways, plus momentary with a pneumatic time delay if you need the release held for a set interval.

Yes, the 9200 Series is built as a narrow stile key switch, so it is sized for the stile of an aluminum storefront or entrance frame rather than a wide flat plate. Glass front installers use it there specifically. The two finishes, satin aluminum (US28) and dark anodized bronze (US40), are the standard storefront anodize colors, so it matches clear and bronze extrusion.

The SDC 700 Series key switch assembly is the closest peer - it is a key switch assembly supplied with a stainless steel faceplate. The ROFU 9200 Series is a narrow stile SPDT key switch offered in Satin Aluminum (US28) and Dark Anodized Bronze (US40), in momentary and maintained action, with options for a bi-colored LED or a pneumatic time delay. If you need the switch to sit in an aluminum stile and match a bronze or aluminum storefront, the 9200 Series covers that; if you are mounting to a stainless faceplate on a masonry or drywall back box, the SDC-700 is the one to look at.

No. The ROFU 9200 Series is a single SPDT key switch for narrow stile mounting, available momentary or maintained. For a combined station, the Dortronics 5246 Series puts one SPDT key switch and two SPDT push buttons on a mini-box console with a two-position key-removable switch. Choose the Dortronics 5246 when one station has to key-enable a circuit and also give operators momentary release buttons; choose the 9200 Series when the key switch alone goes in the door stile.

The pneumatic time delay (model 9969) is field adjustable from 2 to 60 seconds, rated 10A at 125-250 VAC. Turn the key once and the contact stays transferred for the interval you dialed in, which is how you give someone time to walk through a delivery door without anyone standing at the switch. It is ordered as the momentary with pneumatic time delay version.

Order the bi-colored LED version. The LED reads the on/off position of the switch, so staff at the counter can tell whether the opening is released without walking to the door. It is available on both the momentary and the maintained versions, in satin aluminum or dark bronze. It is most useful on the maintained switch, where the unlocked state persists.

The ROFU 9200 is shaped for a narrow stile, so on a standard hollow metal door with a box or gang back box you are better off with a faceplate-style assembly. The SDC 700 Series key switch assembly comes with a stainless steel faceplate, and the SDC 800 Series is a vandal resistant assembly with a 1/4 inch aluminum faceplate for exposed or abuse-prone locations. If you want the key switch combined with push buttons on one console, the Dortronics 5246 Series puts a key switch and two SPDT push buttons on a mini-box console.

Both routes offer indication. The ROFU 9200 Series can be ordered with an optional bi-colored LED showing the on/off position, in either momentary or maintained action and in Satin Aluminum (US28) or Dark Anodized Bronze (US40). On the Dortronics side, the 5236 Series push button console includes one LED. The difference is the control device itself: the 9200 is a keyed narrow stile switch, the 5236 is a push button console.

No soldering. The 9200 Series kit uses pinch-on wire connectors, so an electrician or installer lands the leads with a crimp and moves on. That matters in a stile cavity where you have no room to work an iron.

Yes, it is a commercial-duty electronic access control device, used for key-controlled release of electric locking hardware on storefront and entrance openings. Property managers standardizing a building can run the same switch across multiple doors and key them all to the existing system, since the cylinder is supplied separately.

A key switch restricts the release to whoever carries the key. Where you just want an unrestricted request-to-exit or counter release, a push button console is the simpler part: the Dortronics 5236 Series carries a 3/8 inch diameter DPDT momentary snap-action push button on a mini-box console with an LED. Use the ROFU 9200 where the release has to be key-controlled.
