The iconic vandal-proof pushbutton

Made from solid st/steel, Sherman is DMG’s most reliable and vandal-resistant pushbutton

SHERMAN at a glance

Modern look, minimalist design.
Rock-solid body, tested for vandal-proof requirements of EN81-71 Class 2 (more..)
Pressel made from AISI 303 turned stainless steel (standard or PVD-coated finishes), available in different shapes.
Frontal mounting (no studs), fastening by jam-nut ring.
Single or twin illumination.
IP44 and IP47.


Its minimalist look should not be misleading: SHERMAN is a button designed for demanding, heavy-duty applications.
With its extremely robust body and proven activation mechanism, SHERMAN fully complies with EN81-71 Class 2 European guidelines to design lift components installed in environments prone to vandalism.
SHERMAN was successfully tested in our laboratories for impact, water flow and fire resistance.
See our resistance test.


The EN81-70:2018 norm requires that luminance contrast between adjacent surfaces be evaluated in numerical light reflectance value (LRV).
The tag black metal added around SHERMAN frontal mount button provides enhanced luminance contrast to the surrounding faceplate.



The Sherman button comes in four charming shapes for all needs.


CLASSIC : This version has a dome-shaped pressel and LED illuminated halo


DISC : This version has a flat pressel. Electrical and mechanical features are the same as the Sherman Classic

MOON: This version has a recessed pressel. Same electrical and mechanical features as the Sherman Classic.


CALIFORNIA: Similar to the Sherman Disc, the Sherman California features a raised flat pressel to comply with the California code.


The appeal of solid and robust steel in four different pressel shapes


the effortless allure of brass colored PVD coating in all four shapes!


The frontal mount version of the SHERMAN can be inserted in round-shaped 30mm cut-outs, fastening by the jam-nut ring on 0,8 mm to 3 mm faceplates.
Avalaible adaptation ring for cut-outs Ø 35mm.


Tags & surrounds available


The SHERMAN button can be matched to conventional stainless steel tags with tactile Braille, to Caesar retro-illuminated stamped metal surrounds or to Brutus electro-coloured stainless steel surrounds. The backlit embossed Edge symbol, inserted directly on the faceplate, is a great choice too.


Upon activation the halo of the pushbutton light up in red or blue.
White illumination is also available on request for some pushbuttons.
By default, all DMG buttons are available primarily with this basic illumination pattern.


Like all our pushbuttons, the Sherman can be matched to different contact modules:

Wire terminals contact module

Single Lighting

Good for all types of modernizations. Requires conventional wiring during installation.
If EN81.70 Beep is required, the additional PCB0BEEP module shall be added to the car panel and at each floor. Alternatively, the P8+BEEP contact module is suggested especially at floors.

JST connector
contact module

Best solution for pre-wired fixtures within the Pitagora 4.0 electric system.
A JST cable must be added to connect the push-button to the Pitagora 4.0 boards in the car (C40.COP14) and at each floor (C40.BDU).

Wire terminals
contact module + BEEP

Good for new installations and modernizations requiring acoustic feedback of call registration (EN81.70).
The built-in acoustic device features +/-2dB BEEP signal when button is pressed.
