ROFU 9200 SPDT Key Switch, Standard Stile, 10A/250V-15A/125V

No cylinder is supplied with the ROFU 9200. You order the mortise cylinder separately, and it takes a standard architectural size cylinder, so a common commercial mortise cylinder in your building's keyway will work. That is actually the point for a locksmith: the switch drops onto the existing master key system instead of adding another key to the ring. What does ship with it is the aluminum cover plate, two snake eyes security screws and the wrench for them.

Momentary makes the contact only while you hold the key turned, then springs back. Use it to pulse an electric strike, mag lock release or auto operator for one entry. Maintained holds the position until you turn the key back, so it latches a circuit on or off, which is what you want for unlocking a door for business hours or disabling a mag lock. Both are offered on the 9200, along with a momentary with pneumatic time delay if you need the release held for a set moment without someone standing at the key.

The 9200 is rated 10A at 250V and 15A at 125V, so it will carry a line voltage load as well as the 12 or 24V access control circuits it is usually wired into. It is an SPDT contact, giving you a common with both a normally open and a normally closed leg, so the same switch can release a fail-secure strike or drop power to a fail-safe mag lock depending on which terminal you land on.

The ROFU 9200 already uses a tamper-resistant 1/4 inch thick aluminum cover plate supplied with two snake eyes security screws and a wrench. If you want that same heavy aluminum plate construction from another maker, the SDC 800 Series key switch assembly is also built with a 1/4 inch aluminum faceplate and is described as vandal resistant. Both accept a key switch in a door-frame or wall-mounted plate; the ROFU 9200 is offered in Satin Aluminum (US28) and Dark Anodized Bronze (US40) finishes.

No. The Dortronics 5236 Series is a momentary snap-action push button device - one 3/8 inch diameter DPDT button with an LED on a mini-box console - so anyone can press it. The ROFU 9200 is a keyed switch requiring a standard architectural size cylinder, which is what you want when release must be restricted to keyholders. If you want a keyed device with an LED indicator, the ROFU 9200 is offered in momentary and maintained versions with a bi-colored LED.

The LED versions put a two-color indicator in the plate next to the keyway so staff can see door state at a glance, typically locked versus unlocked or armed versus released. It is offered on both the momentary and the maintained switch. On a maintained switch it is the more useful of the two, since a maintained switch holds a state and the LED is what tells you which state it is holding.

Yes, a momentary two key switch version on a single plate is available. That is the one to order when a single opening needs two separately keyed functions, say a release for the door and a second key for an auto operator or an alarm shunt, without cutting two openings in the stile. Both cylinders are still ordered separately.

Two finishes: US28 satin aluminum and US40 dark anodized bronze. Those are the two standard anodized storefront finishes, so the plate will read alongside clear anodized or dark bronze aluminum door and frame work. Every switch function in the 9200 line is offered in both, so a property manager standardizing across a building can hold one finish across momentary, maintained and LED versions.

The ROFU 9200 is a flush door or wall plate meant to be mounted at the opening, so it is the wrong shape for a desk. For a console, 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. If you only need buttons and an LED with no key, the Dortronics 5236 Series is a mini-box console with a DPDT momentary snap-action push button and one LED.

The ROFU 9200 is supplied only with aluminum cover plates, in Satin Aluminum (US28) or Dark Anodized Bronze (US40). For a stainless faceplate, the SDC 700 Series key switch assembly comes with a stainless steel faceplate. Both are single-cylinder keyed switches, and as with the ROFU 9200 you will want to confirm the cylinder you plan to use, since the 9200 does not include one.

The ROFU 9200 is built around flat cover plates - a standard 4-3/4 inch by 3 inch plate or a narrow 4-3/4 inch by 1-5/8 inch plate - intended for stile and wall mounting. For a self-contained enclosure, the Dortronics 5246 Series mounts its key switch and push buttons on a mini-box console, and the Dortronics 5236 Series uses the same mini-box console format for a push button only.

It is a commercial product, built for electronic access control on institutional and commercial openings. The single cylinder keyed operation, the security screws and the line voltage rated contacts all point at schools, healthcare, multi-family entries and storefronts rather than a house.
