Stainless steel lever, spring & screws.
The deadman handle uses a micro switch for operation. The loading is started when the micro switch is activated. The device has to be held closed while a critical operation is taking place i.e. fueling an aircraft. If the device is released for more than say 1 minute the pump will stop thus preventing in the case of an accident spillage of large quantity of dangerous fuel. The handle has been made light and comfortable and in conjunction with an electrical timer and circuits creates a light easy to handle safety device.
