Unipolar buttons

Unipolar buttons are a common element of electrical installations. They enable low voltage electrical circuits to be switched on. They are most often used as installation connectors to control lighting and signaling in electrical installations in buildings, staircases, corridors and residential and technical home and office spaces. The button mechanism has one panel, the pressing of which short-circuits the working contacts and makes connection within a single circuit .

Unipolar buttons - types

Single-pole push buttons come in two types depending on the way the electric circuits are connected.

  1. In the first variant, they function as a bistable installation switch. Then it acts as a toggle switch, and the working contacts remain closed until the button on the control panel is pressed again. Such single-pole buttons are most often used to control lighting in most household and public electrical installations.
  2. The second type are single-pole, mono-stable buttons. Their design allows you to connect the circuit when you press the flap on the control panel. The contacts are closed at this point, and when the pressure on the switching panel is released, the spring opens the contacts and breaks the circuit and electricity is cut off.

Due to their design, single-pole buttons are also available in surface-mounted and flush-mounted versions. Removable control buttons in surface-mounted versions allow installation without exposing external elements to damage.

  1. Surface-mounted single-pole push buttons are used wherever we use installations outside walls and all kinds of storage areas, as well as outdoors. Connecting within a single electric circuit in surface-mounted buttons is usually secured with the appropriate IP tightness class. Splashproof and dustproof allows for trouble-free operation. Regardless of weather conditions, electricity is supplied to the receivers, and the control is safe for humans.
  2. Flush-mounted unipolar pushbuttons are most often available in the push-button version. The removable outer panel allows for quick installation and the wiring fixing system can be screw or spring loaded. Flush-mounted buttons can be mounted on any surface, both on walls, floors, as well as in table tops and light, warning or recall control panels.

The set of bell buttons includes bell buttons with backlight, buttons with key labeling (e.g. labeling as a bell at the top or bottom of the key), wireless bells that do not require wiring, but only a battery power supply, flush-mounted bell buttons without a frame, buttons intended for for multiple frame systems, standard connectors with IP 20 protection level, but with the option of installation as in the case of a connector at IP44 level, i.e. a product more resistant to moisture or dust.

Installation Connector - Application

Thanks to the multifaceted and diverse offer, single-pole buttons can be easily adapted to specific needs. Their most common location is near the entrance doors to apartments and buildings, where they control bells and are used to connect within a single circuit. Surface-mounted and flush-mounted buttons are available in versions with LED backlight, most often red or blue. This makes it easier to locate them in dark corridors, regardless of the time of day. LED lamps can also inform about the state of the installation controlled by the button.

Single-pole buttons with a lamp and a backlight work in typical electrical installations with voltage up to 250 V and current up to 10A. The symbol of a bell, lamp or no designation of purpose allows universal target locations and any button mounting. As an installation fastener, they are used in basements, warehouses, production plants and residential buildings of all kinds.
