A buzzer is a mechanical, electromechanical, magnetic, electromagnetic, electro-acoustic or piezoelectric audio signalling device.

Combination display light or combined indicators show the status of the machine or panel.
Multiple indicators can be combined together. 

Counters, widely used in manufacturing lines and automation systems, display and control received pulse signals from input devices.

Emergency button is now state-of-the-art, providing safety for Man and the machine. We offers a wide range of Safety Components for the protection of Man, machines and production goods in emergency situations.

It is the purpose of an Emergency-Stop device to deflect or minimize the risk as quickly as possible and optimally in the event of an emergency arising. 

A disconnector, disconnect switch or isolator switch is used to ensure that an electrical circuit is completely de-energized for service or maintenance.

An isolating switch must provide a reliable connection in case of a random occurrence of a short circuit in the network.

A limit switch is an electro-mechanical device that consists of an actuator mechanically linked to a set of contacts. When an object comes into contact with the actuator, the device operates the contacts to make or break an electrical connection.

A miniature snap-action switch, also trademarked and frequently known as a micro switch, is an electric switch that is actuated by very little physical force, through the use of a tipping-point mechanism, sometimes called an "over-center" mechanism.

Mono-lever switches operate in four directions using a single lever. Switch contacts are actuated in the direction in which the lever is pushed, enabling quick and accurate control in any desired direction. Ideal for machine tools and industrial machines.

A siren is a loud noise making device. Civil defense sirens are mounted in fixed locations and used to warn of natural disasters or attacks. Most fire sirens are single tone and mechanically driven by electric motors with a rotor attached to the shaft. Some newer sirens are electronically driven speakers.

The main function of a power push button is to turn on / off a device / machine.
It is pushbutton-based latching power control, where one button turns on power and another button turns it off.

A push-button (also spelled pushbutton) or simply button is a simple switch mechanism for controlling some aspect of a machine or a process. Buttons are typically made out of hard material, usually plastic or metal. The surface is usually flat or shaped to accommodate the human finger or hand, so as to be easily depressed or pushed. Buttons are most often biased switches, although many un-biased buttons (due to their physical nature) still require a spring to return to their un-pushed state. Different people use different terms for the "pushing" of the button, such as press, depress, mash, hit, and punch.

There are various types of accessories for the push buttons as enchancements. 
Legend plates, Emergency Stop Guards, Push Button covers, Enclosure boxes are used together with the push buttons.

Revolving Warning Lights are used as visual alerts. 
It is  arranged as to appear and disappear at fixed intervals, either by being turned about an axis so as to show light only at intervals, or by having its light occasionally intercepted by a revolving screen.
This can be done by electronic or mechanical motor. 

A solid-state relay (SSR) is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals.  It serves the same function as an electromechanical relay, but has no moving parts. The relay may be designed to switch either AC or DC to the load.

A switched-mode power supply (switching-mode power supply, switch-mode power supply, switched power supply, SMPS, or switcher) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.

Stack lights (aka: signal tower lights, indicator lights, AndOn lights, warning lights, industrial signal lights, tower lights and light towers) are commonly used on equipment in industrial manufacturing and process control environments to provide visual and audible indicators of a machine state or process event to machine operators, technicians, production managers and factory personnel.
