KP - Single Key Bolt Interlock with Safety Switch
Description

The KP Lock is a key operated mechanical bolt interlock complete with electrical contacts suitable for the control of electrical switchgear or valves.

Both the KP1 and KP2 unit come with a 16mm diameter bolt of variable length, that is used to control the rotation or movement of operating handles or toggles. The KP1 comes with 1N/O 1N/C 10amp contacts and the KP2 2N/O 2N/C 10amp contacts, these are used to provide remote indication of the bolt position on the machine.

The locks are manufactured in brass or stainless steel making them ideally suited touse in harsh or corrosive environments.
Operation
The bolt movement and the switch condition are directly controlled by the rotation of the key. The retraction /extension of the bolt changes the switch contacts condition. The bolt length can be varied to suit the application but the travel of the bolt from extended to retracted is always 19mm. The bolt length should be specified on ordering by quoting the L dimens ion, this being the length of the bolt protruding from the end face with the key in the trapped pos ition and the bolt retracted.
Typical System
The KP is des igned to operate as part of an integrated safety system, controlling the operation of HV/LV switchgear or valves . A typical example is shown below.
