Access Control Touch Switch
This square touch exit button provides contactless door release for access control systems. It operates on 12 V DC input and features a blue backlight that turns red when activated. The unit measures 86 by 86 by 25 mm and weighs 0.105 kg.
Indoor Entry Points Only
Suited for standard gate frames where a single touch switch controls one door. It is not designed for outdoor exposure beyond the rated temperature range or for installations requiring wireless or networked unlocking. Buyers who need multi-door coordination or remote management should look at other solutions.
NO/NC/COM Contact Output
The switch provides normally open, normally closed and common contacts rated at 3 A at 12 V DC, allowing direct wiring to most electronic locks and controllers. This contact arrangement is the key specification that determines compatibility with your access control hardware.

Questions about this item
What items come in the package and what must I buy separately?
The package includes the door switch button, wiring and instruction sheet, and two screws. You will need to supply a DC12V power source and any mounting box or conduit separately.
Which version should I choose for a standard gate frame?
This single square model measures 86 by 86 by 25 millimetres and fits all kinds of gate frames; no other versions or capacities are offered.
What does the 3A at 12VDC contact rating mean when the button is wired to a lock?
The NO, NC and COM contacts can switch up to 3 amps at 12 volts DC, so they can directly drive most electric strikes or magnetic locks without an extra relay.
