DynaLock 6266 Series Latching Palm Switch Buttons, Twist Reset, SPDT Form “Z”

The DynaLock 6266 palm switch stays actuated once it is struck. Hit the palm button and the contacts transfer and hold there, releasing the lock until somebody twists the button to reset it. A momentary button, like the Securitron PB3, only holds the contacts while a finger is on it and the door relocks the instant it is let go. Use the latching type where the opening has to stay unlocked until staff deliberately restore it, such as an emergency egress or a hold-open condition, and use a momentary or maintained button where you want a simple release-and-relock request to exit.

Form Z is a single pole double throw contact set, so the 6266 gives you one common with a normally closed and a normally open leg that transfer together when the palm is struck. Wire the normally closed side in series with the power feed to the mag lock or strike so the strike drops when the button latches, and use the normally open side to signal the alarm panel or access control input at the same time. One button, both jobs, no extra relay needed.

Both, but you have to pick the plate. The standard faceplate mounts to a single gang box. There is a narrow plate option at 1-3/4 inches wide for mounting on a hollow metal frame or a narrow mullion where a standard plate would overhang, and a two gang faceplate option at 4-9/16 inches wide when you need the extra real estate. Measure the flat of the frame first, because 1-3/4 inches is the width that decides whether this lands on a mullion at all.

If a hold-until-reset action is more than the opening needs, a few alternatives cover the simpler cases. The RCI 908 Series electronic exit button has red EXIT text and maintained operation. The RCI 919 Series is a rotary release button, also maintained, in satin aluminum. The Securitron EEB is an emergency exit push button with interchangeable LED lenses. For a plain momentary request to exit, the Securitron PB3 or the illuminated PB4L and PB5 buttons cover it, and the RCI 950 Series round push plate carries a handicap symbol for accessible openings. The 6266 is the choice when you specifically want the palm strike to latch and require a twist to restore.

Both are commercial push button request-to-exit controls. The DynaLock 6266 is a latching palm switch with twist reset and SPDT Form Z contacts, so the button stays actuated after it is struck and has to be twisted to return to normal. The Securitron PB3 is a push button switch. Where an opening needs the release to hold until someone deliberately resets it, the 6266 twist reset behavior is the one that does that; where the release should clear as soon as the hand leaves the button, the PB3 family is the direction to look.

They are the closest pair in behavior. The RCI 919 is a rotary release button with maintained operation, so like the 6266 it holds its state once actuated and is returned by turning it rather than by releasing pressure. The 6266 is a palm switch, sized to be hit with the flat of a hand, and carries SPDT Form Z contacts. The RCI 919 is offered in a satin aluminum finish while the 6266 is brushed stainless steel US32D, so on an opening where the plates are being matched the finish is the thing to confirm before swapping one for the other.

Look at a momentary device. The RCI 950 Series round push plate with handicap symbol is a momentary switch in satin stainless steel, and the ACSI 1320-1-MOM-ER is a momentary pushbutton marked Emergency Release. The RCI 909 Series is a flush mount momentary rocker switch rated 250VAC 10A. All three return on their own when pressure is removed, where the DynaLock 6266 latches and is cleared by twisting the button.

The DynaLock 6266 is available on a narrow plate 1-3/4 inches wide, which is the configuration to specify for a narrow stile. If a purpose-built narrow device is wanted instead, the Trine 342 is a narrow style electric door switch. The 6266 in its narrow plate form still gives the latching twist reset action; the Trine 342 is a different switch and its operation should be confirmed against what the opening needs.

The anti-tamper switch is a separate contact that reports if the plate is pulled off the box, and it is available on every configuration of the 6266, with or without the LED and on any of the plate sizes. Institutional and multi-family jobs that monitor egress points usually want it, because a latching emergency release button on a public corridor is a target for defeat, and the tamper contact gives the panel a supervised input on the device itself.

Order the 6266 with the narrow plate, 1-3/4 inches wide, which is sized for a frame face or mullion that a standard plate overhangs. If you need something narrower still or a different action, the Trine 342 is a narrow style electric door switch built for the same tight mounting problem. Get the frame face measured before you commit, because the plate width, not the switch, is what decides this.

Yes, and the difference is who can operate it. The 6266 palm switch is open to anyone in the space, which is what you want for egress, while a keyed release like the ACSI 1310-1 mortise keyswitch restricts operation to someone carrying the key. Plenty of openings get both: a palm switch on the egress side for emergency release, a keyswitch for authorized staff control. The 6266 interrupts the lock feed through its normally closed contact, so it works on a maglock or an electric strike wired fail safe.

Sixteen combinations, built from four choices: anti-tamper switch yes or no, bi-color red/green 12/24 VDC LED yes or no, narrow 1-3/4 inch plate yes or no, and two gang 4-9/16 inch faceplate yes or no. On top of that you must answer the audible sounder question, and the sounder is only available with the two gang faceplate. Settle the plate size against your frame first, since it constrains the sounder, then add the tamper contact and LED to suit what your panel monitors.

The DynaLock 6266 can be ordered with a bi-color red/green LED at 12/24 VDC as an option on the button itself. If the illumination is the point of the device, the Securitron PB4L is an illuminated halo with a stainless push button, the Securitron PB5 is a medium round illuminated push button, and the Securitron EEB emergency exit push button uses interchangeable LED lenses. Those are momentary-style exit buttons rather than latching palm switches, so they do not reproduce the 6266 twist reset behavior.

No. The ACSI 1310-1 is a mortise keyswitch, actuated by a key in a cylinder, so it restricts who can operate the door release. The DynaLock 6266 is a palm switch anyone can strike with a hand and is reset by twisting the button. They are used for opposite intents: the keyswitch controls access to the function, the palm switch makes the function fast and unmistakable to reach.

Both hold their state after actuation rather than springing back. The RCI 908 Series is an electronic exit button with red EXIT text and maintained operation in a 32D finish. The DynaLock 6266 is a latching palm switch reset by twisting, with SPDT Form Z contacts and a red button as standard, in brushed stainless steel US32D. The RCI 908 labels the function in text on the plate; the 6266 relies on the palm-sized button and its red color to be found by hand.

They are different devices for different intents. The RCI 950 Series is a round push plate carrying the handicap symbol, a momentary switch in satin stainless steel, used where the door release is meant to read as an accessibility actuator. The DynaLock 6266 is an unmarked latching palm switch in brushed stainless steel US32D with twist reset. If the opening calls for a marked accessibility actuator, the 950 carries the symbol; if it calls for a release that stays engaged until reset, the 6266 does that.

It is a commercial device, catalogued for door hardware duty rather than residential. That matters for a palm switch because the whole point of the form factor is that people hit it hard, with a forearm, a gloved hand or a cart, in traffic that a residential-grade button would not survive. Standard finish is brushed stainless US32D over a metal plate, which is what holds up on a hospital, school or parking structure corridor.

Brushed stainless steel, US32D, with a red button as standard. US32D is the default commercial finish on most hollow metal openings, so the plate matches the pulls, push plates and exit device trim already on the door in nearly any institutional corridor. The red button reads as an emergency release at a glance, which is the point on a latching palm switch.
