HZTK
Door switch and hook lock positive contact
The innovative HZTK is a safety switch with forced actuation which can be used as door switch and switch for locking mechanism. It allows a large sliding area between contact bridge and switch. In addition to the standard design (HZTK-1), a higher version is available (HZTK-2), at which the connection cables can be laid below the switch.
