Schlage Electronics 660-PB Station Control, SPDT Momentary Pushbutton

The 660-PB is a momentary SPDT pushbutton station used to release an electric or electronic lock from a remote spot. Press it, the contacts transfer for as long as you hold, and the lock releases; let go and it returns. The classic install is under a reception desk so staff can buzz someone in at the entrance door without leaving the desk. It is a release switch only, not a lock or a power supply.

The mini aluminum box measures 2 x 2 x 1 inches, which is what makes it work in the concealed desk application it is built for. It surface mounts, so you are not cutting into the desk apron or fishing a back box into millwork, just fastening the housing to the underside and running wire back to the lock power supply.

Depends on whether you want the door to unlock while you hold it or stay unlocked until you go back and change it. The 660 Series comes both ways: the 660-PB is the momentary action pushbutton, so the lock releases only while pressed, and there is a maintained action toggle switch version that stays in whatever position you leave it. For buzzing a single visitor in at a reception desk, momentary is the one. For holding a door unlocked through business hours, the toggle is what you want. Both surface mount in the same mini aluminum box.

Yes, because it is SPDT. A single pole double throw switch gives you a common plus a normally open and a normally closed contact, so you can take the NO side for a fail secure electric strike that needs power to release, or the NC side to break power to a fail safe magnetic lock or electric lock. One switch covers either lock type, you just land the wire on the right contact.

Both are pushbutton release stations wired to an electric or electronic locking device, but they are built for different mounting situations. The Schlage Electronics 660-PB is an SPDT momentary pushbutton in a 2 in. x 2 in. x 1 in. mini aluminum box, surface mounted, and intended for concealed desk application - the classic under-the-counter button a receptionist reaches for without looking. The Locknetics IPB-100 and IPB-100-N are illuminated pushbuttons from the IPB Series, so the button face itself is lit, which suits a station the user has to see and aim for - a wall position in a corridor, a lobby, or a dim vestibule. Choose the 660-PB when the button lives out of sight under a desk and is found by feel; choose an illuminated IPB station when the button is in public view and needs to be visually located.

Not the right pick for that. The 660 Series mini station is built for concealed desk application, mounted out of sight under a desk so someone at a station can release the entrance door. If you want a button people see and press at the door itself, look at an illuminated wall pushbutton like the Locknetics IPB-100 or IPB-100-N instead, which is made to be seen and found.

Different jobs. The 660-PB is a small momentary SPDT station in a 2 x 2 x 1 inch aluminum box meant to be hidden under a desk, so the person releasing the door is staff, not the visitor. The Locknetics IPB Series is an illuminated pushbutton, so it lights up and is meant to be located by whoever is walking up to it. Pick the 660 for a discreet staff release, the IPB when the button itself has to be visible at the opening.

The station is the switch only. To finish the job you still need the locking device itself, an electric strike, electric lock or mag lock, plus the power supply that feeds it, and the wire run from the desk back to the door. The 660-PB breaks or makes that circuit from the remote position; it does not supply power and it does not lock anything on its own.

For an exposed wall position, look at an illuminated station such as the Locknetics IPB-100 or IPB-100-N from the IPB Series, where the button face is lit and can be found visually. The Schlage Electronics 660-PB is a momentary SPDT pushbutton designed for concealed desk application, mounted in a small 2 in. x 2 in. x 1 in. aluminum box on the surface - a typical use is under a desk to release an entrance door, where the operator knows where it is by touch. It will still switch the lock the same way in a wall location, but it gives the user no visual cue in low light. Match the station to how the person will find it.

Treat it as a different station rather than a drop-in. The Schlage Electronics 660-PB is supplied in the 660 Series mini aluminum box measuring 2 in. x 2 in. x 1 in. and is surface mounted for concealed desk use, so the existing opening, box and mounting screws in a desk installation are sized to that housing. The Locknetics IPB-100 and IPB-100-N are IPB Series illuminated pushbuttons - a separate product family with its own housing and an illuminated button face that draws power for the lamp. Swapping families means re-cutting or re-mounting the station and accounting for how the new button is wired, so plan it as a station change, not a button change.

One 660-PB is one SPDT circuit, so it switches one lock circuit. If a receptionist has to release two separate entrance doors independently, order a station for each. Where two locks are on the same circuit and always release together, a single station can carry them as long as the load stays within what the switch and power supply are rated to handle.
