FAQ
TL;DR: Quadruple bell-type wall switches exist, but selection is thin; wireless quads advertise 300 m range, and “the market with such a momentary button option is poor and manufacturers set prices from space.” [Elektroda, gradek83, post #17454385]
Why it matters: This FAQ helps homeowners and integrators find non-touch, normally-open, momentary multi-key switches that fit standard flush installations without KNX.
Quick Facts
- Confirmed option: a quadruple “przycisk zwierny” module in mainstream frames (B.kwadrat/B.3/B.7) is available. [Elektroda, mawerix123, post #17455269]
- Designer quads like CJC LISA exist, but users report pricing as “from space.” [Elektroda, gradek83, post #17453461]
- Wireless alternatives include 4‑channel LD22 sets and quad bell panels claiming 300 m range. [Elektroda, gradek83, post #17454385]
- Six buttons in one frame typically pushes you to touch panels; four mechanical buttons fit more readily. [Elektroda, w_szymek, post #17459074]
- Ergonomics note: Livolo’s narrow keys can be hard to hit, per user feedback. [Elektroda, gsmphone, post #17454269]
What exactly is a “quadruple, bell-type, non-touch” switch?
It’s a four-key wall control with normally-open contacts that spring back when released. It’s mechanical (non-touch) and intended for flush mounting. The request excludes tactile/capacitive touch panels and KNX bus keypads. This style works well with intelligent relay installations that expect momentary inputs. [Elektroda, gsmphone, post #17450802]
Which models in this thread match a true quad momentary?
A confirmed example is the quadruple “przycisk zwierny” in the B.kwadrat/B.3/B.7 series, shared with a video showing its operation. It provides four momentary keys in a single frame. Check finish and frame compatibility within the same program family before ordering. [Elektroda, mawerix123, post #17455269]
Is the VL‑W104‑WC glass panel actually momentary?
It’s listed as a “quad switch,” but the momentary function isn’t stated. The advice here is to request confirmation and a datasheet from the seller before buying. As one expert put it, “you would have to ask.” [Elektroda, gradek83, post #17454178]
Are Siemens DELTA bus buttons suitable if I don’t want KNX/touch?
DELTA profile bus buttons are presented for switching, dimming, and blind control with combination frames. They are bus-type devices, so confirm electrical compatibility with your system if you require simple dry-contact momentary inputs. Verify price and local distribution before committing. [Elektroda, gradek83, post #17454178]
Are shutter-labeled double buttons okay for general use?
They can function, but the shutter iconography may confuse users. In this thread, the louvre/blind double momentary option was rejected because it suggests controlling blinds rather than general scenes or lights. Consider neutral icon caps to avoid mismatched expectations. [Elektroda, gsmphone, post #17453530]
Can I use wireless quads if my home is already wired?
You can, but the OP avoided them due to batteries and aesthetics. One wireless quad bell panel is battery-powered, while a 4‑channel LD22 set was a latching switch, not a bell-type. Wired momentary inputs suit pre-run cabling and avoid battery maintenance. [Elektroda, gsmphone, post #17455216]
Why are quad momentary wall switches expensive and rare?
Niche demand reduces competition and keeps prices high. As an expert noted, “the market with such a momentary button option is poor and manufacturers set prices from space.” Designer lines add cost for materials and aesthetics. Expect limited availability and higher pricing. [Elektroda, gradek83, post #17454385]
I need six buttons in one frame — is that realistic?
One user asked for six, but feedback indicates four momentary keys is the practical mechanical limit for a standard frame. Six-key mechanical layouts usually require custom work or moving to touch/capacitive panels that multiplex inputs. [Elektroda, w_szymek, post #17459074]
Any DIY/custom approach to get 6 physical buttons?
Yes. One approach is adapting a blank plate and installing six panel-mount momentary pushbuttons. A fabricator can water‑jet cut precise holes. You can use illuminated INOX bell buttons for clarity. Ensure depth and wiring clearances within the flush box. [Elektroda, gradek83, post #17456996]
Can LD22 or similar 4‑channel wireless be used as a bell switch?
No, not as‑is. The LD22 example is a latching switch rather than a momentary bell‑type. Another wireless quad is momentary but battery-powered, which the OP rejected due to existing wiring. Choose true momentary, wired modules for bell input logic. [Elektroda, gsmphone, post #17455216]
Where can I see a working demo of a quad momentary?
A video linked in the thread demonstrates the operation of a quadruple momentary module from the B.kwadrat/B.3/B.7 family. Watching it helps confirm the travel, return action, and user interaction before purchase. [Elektroda, mawerix123, post #17455269]
Any brands to avoid or watch for quality issues?
One user reported BERKER 535034 04 as poor quality with “sticking.” Test samples if possible, and confirm return policies. Edge case: sticky keys can mis‑trigger scenes and frustrate users. [Elektroda, evlo2, post #20387118]
Do Karlik DWP‑10/11 or Simon DEW4 have bell‑type modules?
The thread raises these options but lacks schematics or confirmation. Simon DEW4 is described as “electronic,” which leaves behavior unclear for dry‑contact bell usage. Request datasheets or wiring diagrams from the manufacturers before deciding. [Elektroda, evlo2, post #20387118]
How do I verify “momentary” before I buy?
Follow this quick check:
- Look for terms like “momentary,” “bell,” or “NO” on the product page.
- Ask the seller for a datasheet confirming spring‑return behavior.
- Bench‑test continuity to confirm normally‑open contacts that break on release. [Elektroda, gradek83, post #17454178]
I need multiple units — any planning tip?
Costs multiply quickly when buying several. One user needed five total units, which made premium options impractical. Plan scenes and circuit groups to minimize wall clutter, and standardize on one frame system to streamline purchasing. [Elektroda, gsmphone, post #17453530]
