FAQ
What are pushbuttons and switches?
By activating a pushbutton or switch, its switching status changes and a function that is related to it will be activated on the machine or plant. Typical examples are emergency-stops, pushbuttons, selector and key switches, but also capacitive or contactless switching elements.
What is a signal device?
Signal devices indicate a change in status on a machine or plant via a visible or audible signal. Typical examples of signal devices are optical or acoustic signal generators like pilot lights, signal towers or sirens.
What is a normally closed (NC) contact?
A switching contact is called a normally closed contact when it opens an electrical circuit and thus interrupts it. In idle state, the circuit is closed and electricity flows to the consumer. If the switching contact is actuated via a pushbutton or switch, the circuit is being opened and the electricity flow to the consumer is disrupted.
What is a normally opened (NO) contact?
A switching contact is called a normally opened contact when it closes an electrical circuit. In idle state, the circuit is opened and the electricity flow to the consumer is disrupted. If the switching contact is actuated via a pushbutton or switch, the circuit is being closed and the consumer is supplied with electricity.
What is an inverter?
A switching contact is called an inverter when it changes the state of two circuits at the same time. In idle state, the first circuit is closed while the other one is opened. If the switching contact is actuated via a pushbutton or switch, the state of each circuit changes into that of the opposite: The first one is being opened and the other one is being closed simultaneously.
What is the difference between a pushbutton and a switch?
A pushbutton is not a switch: The difference between both lies in their state after being actuated. A pushbutton will return to its initial position after being actuated, while a switch will stay in its new position. Typical examples for a pushbutton are a doorbell or the button of a mouse. For a switch typical examples are a light switch or the switch of an oven.
