Two leaders in switching applications, now connected.

KISSLING is now part of TE Connectivity (TE). Together, we offer customers a wide range of switching products and solutions for virtually all applications, including those in the harsh environments. KISSLING relays and switches offer a broad spectrum of products, with both both standardized and custom options.

TE's KISSLING brand is synonymous with high-quality ruggedized and sealed switching solutions, designed for extreme operating environments including shock, vibration, temperature and humidity. E-vehicles and power management systems are part of a fast-growing industry that bring new application requirements to light. Our focus is to cover high power, high voltage and control switching applications.


Our designs and our attention to production quality and product reliability result in a product line of relays and switches for both power distribution and control applications. Even as we continue to grow and expand, we pride ourselves on the ability to develop and maintain close working relationships with our customers in all the markets we serve, understand their requirements and provide both standardized and custom switching solutions.


KISSLING products perform wherever switches and relays need to operate reliably under extreme conditions for demanding applications. TE's KISSLING brand has built its reputation on solving customer requirements for switching applications with very high contact ratings, critical environmental conditions such as humidity, pressure, dirt, aggressive fluids or increased shock and vibration stability.


Our broad spectrum of relays and switches combined with the wealth of experience resulting from years of practical application work, makes TE a solution partner for applications with exclusive switching requirements.


KISSLING brand relays are built for long life under extreme operating conditions. Features include:

  • Highly stable insulating materials suitable for extreme environmental conditions (non-gas filled relays)
  • Robust contacts for long contact lifecycle
  • Sealing technology that meets or exceeds the IP67 & IP6K9K standard
  • Mono-stable and bi-stable magnetic circuits
  • Single and dual coil switching systems
  • Special compact and light weight versions for aviation and racing applications; 
  • On-board control electronics for switching onboard power supplies, monitoring over and under voltage, or preventing deep discharge of batteries
  • 12V- 600VDC and 20A to 1000A continuous DC power with 100% duty cycle
  • 10,000 – 100,000 switching cycles under full current load and up to 2 million cycles mechanical life



KISSLING High Power Relays

Our relays series are environmentally sealed relays with protection standards IP67and IP6K9K (Steam pressure cleaning). The high power relays have a continuous amperage rating from 75 Amps to 500 Amps and two different types of coil systems. The single coil as well as the dual coil system features high shock and vibration resistance predominantly from careful design and an optimized magnetic circuit.


The series is available with a wide variety of configuration options including contact configurations (NO, NC, NO/NC), coil voltages (12 V, 24 V, 36 V, 48 V, 60 V, 72 V and 80 V) and various bracket styles to meet your installation conditions. Also available are optional suppression devices to eliminate electromagnetic interference at the coil and optional auxiliary contacts.


Other important advantages are low heat generation in the contact area based on low contact voltage drop, a compact design, low holding current, silver alloy contact material and the use of mechanical and high thermal stability insulating compounds. Both the terminals and housing are corrosion resistant.


The KISSLING brand portfolio offers a bi-stable relay-series. These relays are suited for power distribution applications requiring low power drain and features extremely high shock and vibration resistance resulting from careful design and an optimized magnetic circuit.

Relays are available with a NO contact configuration and both 12V & 24/28V coil voltages. Various bracket styles are available to enable solutions for your installation conditions. Also available are optional suppression devices to eliminate electromagnetic interference at the coil and optional auxiliary contacts.


Detailed information regarding the various types is available on request. Custom relays can be developed in accordance to client specifications.


Intelligent KISSLING Relays

This relay series has all of the same quality mechanical and electrical switching characteristics - but also features additional electronic functions for pulse protection of the coil, a low energy switching input for direct connection to an ECU, as well as an optional "energy" function for fail-safe shutoff when power is lost.


Other important advantages include a two pin coil control which allows this relay to serve as a drop in replacement for a mono-stabile relay in application where the power drain of a mono-stabile relay is an issue. The electronic functions directly coupled to the relay not only reduces peripheral circuitry and costs in the vehicle itself, but also improves safety levels in critical switching applications.


The smart relay series includes power relays in nominal voltages of 12 & 24 V and nominal continuous amperages of from 200 Amps to 300 Amps.


These relays are suited for battery management and power distribution applications on commercial vehicles, buses, construction & agricultural vehicles, aircraft, ground support equipment and lift trucks.

KISSLING Manual Switches


KISSLING switches are built for long life under extreme operating conditions. All KISSLING brand switches profit from our decades of experience with leading edge technology like:

  • Highly stable insulating materials suitable for extreme environmental conditions
  • Long mechanical lifetime
  • Sealing technology that meets or exceeds the IP67 / IP6K9K standard

This broad product line has evolved over decades and covers a wide variety of industry needs, but we also recognize the individual needs of our customers and customized solutions are a key part of our business. Our product portfolio includes a wide range of various product types, we offer HMI Switches, robust encapsulated switches, plunger switches and micro switches.


Typical Applications:


  • Commercial vehicles
  • Special vehicles
  • Plant and industrial engineering
  • Special suitable as system start/stop in various kinds of mobile application and in control panels also with remote control function

KISSLING Sealed Battery Disconnectors

Our manually operated battery disconnectors range from 200 A to 500 A, meeting the most demanding requirements in vehicle applications.


The nominal current ratings refer to continuous DC current at up to 100% duty cycle and the switches are built to switch under full load and can handle up to 5 times the continuous current level for up to 10 seconds as overload current.


All single or dual pole battery disconnectors are sealed with a technology that meets or the IP 67 and IP6K9K (steam cleaning) standards and the switches are designed to operate at temperatures between -40°C and +85°C.


Battery disconnectors from TE's KISSLING brand can be operated under full load, to confirm in emergency conditions a safe disconnection from the battery.

Power Distribution Solutions

E-Mobility is playing an increasingly important role in the design of new generation commercial vehicles, including trucks, buses, construction and working vehicles. The move to electric drive systems brings a number of environmental advantages but also poses some major challenges with handling high on-board power and charging currents and meeting stringent safety requirements under possibly harsh operating environments.


TE is a manufacturer of robust components and systems for power switching and distribution in all types of heavy vehicles. We have developed complete power distribution systems covering the 480V – 900V range current used in the heavy vehicle E-mobility market segment.


TE's KISSLING brand also includes high-power press-fit PCB technology for use in HV power distribution units. By replacing conventional cable harnesses with high power PCBs (up to 1000A continuous) and replacing solder connections with low resistance press-fit (cold-weld) connections, we offer highly reliable power distribution solutions for vehicle manufacturers. These solutions are generally custom designed for your application and our team of experienced engineers are prepared to work with your specific requirements.


KISSLING brand solutions are in use today in trucks, buses and a wide variety of military and specialized vehicles all over the globe.
