Abstract (en)
[origin: WO2015118087A1] A system for performing an operation comprises a key (70) defining a key code in hardware, a key reader (78) for reading the key code from the key, a tool (4a, 4b, 4c) having an operative arrangement (4d, not shown) for performing an operation and a code-activated switch arrangement (50) which defines an activation code in hardware and a power source (32). The key reader and the code-activated switch arrangement are configured for communication. The code-activated switch arrangement is configured so as to selectively define at least part of an electrically conductive path from the power source to the operative arrangement according to whether a key code received from the key reader matches the activation code. Such a system may reduce the risk of unintentional connection of the power source to the operative arrangement thereby reducing the risk of unintentional activation of the operative arrangement.
