The Heil FS-2 is a unique product specially designed for controlling two devices simultaneously. A typical application would be to key a transceiver with the BLACK lead and an RF power amplifier with the RED lead. Because of the design architecture, the micro-switch controlling the RED lead keys up first as the foot switch is depressed, thus the RED lead turns on before the BLACK lead thus insuring that the amplifier is keyed first before drive is applied from the transceiver that keys up last in the sequence.
The Heil FS-2 features an ergonomically correct foot switch with the hinge under your heel which requires much less effort and relaxes the shin muscles during long periods of operation, such as contest and DxPedion operations.
