Push Buttons

from renown manufacturers

Push Buttons transfer operator’s pushing action to the machine. They enable you to start and stop your machines or processes by maintaining the control of the system.

Top-quality push buttons for reliable control

Schmersal push buttons

We offer an extensive variety of push buttons (also known as the push button switches). A compact- (all-in-one) as well as a time- and cost-efficient modular designs are available. Some push buttons also feature the high level of contact reliability achieved by using self-cleaning auxiliary contacts suitable for electronic circuits.

Use push buttons in different applications

Especially in industrial environments, many different machines make people’s lives easier. But for the machine control in the industrial applications, the human-machine interfaces are needed, and this is where push buttons come in handy. The push buttons that are ergonomic to operate and ensure transparency and information in the human-machine interface are one of the key prerequisites for the streamlined, efficient production.

The manual actuation of these devices starts or stops operating sequences and functional processes even under extreme conditions such as frost, dust or heat. As the link between human and machine, they are used in e.g., operator control panels of production and material handling plants, on conveyors, in elevator construction, in dashboards of ships, in the cockpit of industrial vehicles, etc.

BENEDICT Types of pushbuttons

Push buttons come in various types, each having a different function, e.g.:

The flush push buttons require direct pressure on the operator’s surface. They have the actuator flush with the mounting ring. They are often used as start buttons that need to be protected from accidental initiation.

The extended push buttons have the actuator protruding beyond the mounting ring. This allows you easier activation as you do not need to place a finger squarely on the actuator to operate the push button. Such buttons are usually used for the most prominent commands on an automation panel.


The mushroom-head push buttons have actuators that extend over the edges of the mounting ring and have a diameter larger than a standard push buttons. Because of their size and shape, they are better visible and more easily actuated. Consequently, they are often used as emergency-stop buttons.

The illuminated push buttons mostly use integrated LEDs to provide the desired illumination. They combine actuating and illuminating functions, saving space and reducing cost.

The double push buttons combine two operators in one housing, saving space and reducing cost. Some models have an additional illumination function.

Check color coding of push buttons

Every color of a push button has a unique meaning:

  • Red stands for “emergency”; the button is actuated in the event of a hazardous condition or emergency
  • Yellow stands for “abnormal”; the button is actuated in the event of an abnormal condition
  • Green stands for “normal”; the button is actuated to initiate a normal condition
  • Blue stands for “mandatory”; the button is actuated for a condition requiring mandatory action
  • White has no specific meaning assigned; the button is actuated for general initiation of functions except for emergency stop
  • Black has no specific meaning assigned; the button is actuated for general initiation of functions except for emergency stop

Main parts of push buttons

BENEDICT Modules of pushbuttons

The push buttons consist of:

  • Auxiliary contact is the conducting part of a switch that establishes or breaks a circuit. The circuit is open in its “neutral” state and closed in its “closed” state. The activation of the operator will reverse the neutral state of the contact.
  • Contact block encapsulates the contact. Blocks are held to the back of a device with a contact block holder.
  • Operator/Actuator is the part of the device that is touched to operate.
  • Lamp block holds and activates the light bulb when it receives the appropriate signal.

Modular models are installed by combining these parts like a LEGO, so individual parts can be replaced easily when necessary. On the other hand, compact models are all-in-one devices and the whole push button must be replaced.
