At the time, production, design, and sales of key-operated interlocks took place in our parentsí garage! Ourís would have been a short story, if not for the support of our very first customers and suppliers. Because of their original commitment to us, absolute customer orientation is the number one priority for our colleagues and us.

Advantages of Haake key-operated interlocks

Benefits offered by the trapped-key system, e.g. key-operated interlocks:

- high safety, individual codes
- only pre-determined sequences securing safety are possible
- no spare tongue "in the pocket"
- no cables to the individual guards (cost saving, faults prevented)
- easy retro-fitting
- key-operated interlocks have locking feature
- particularly suited when there are different energy sources for the machine (electric, pneumatic, ...)
- in areas where people might get trapped: personal safety key
- simple possibilities for teach in
- time delay due to key transfer between switch and guard interlock - run-down processes come to a standstill (if necessary, extend by additional unit)

Switch HST-S and key-operated interlocks

key-operated interlocks: The switch HST-S is used for isolating the machine, in order to permit safe access. After the voltage has been switched off, the previously trapped key can be removed and used for the next step in the sequence, e.g. opening a guard. The unit is available as an enclosed (IP 65) or a panel mount version. Versions with multiple locks (enclosed version sheet-steel up to 4, panelmount version up to 10) are also available. Further, versions in explosion-proof enclosures (ATEX zones 21 & 22 and 1 & 2) can also be supplied.
