From 
Over twenty years ago I made PTT foot switch for contestsThe design was based on a body made of cuprextite connected by hinges, a screw with a spring and a pair of microswitches. Such a switch still works today and has been tested by tens of thousands of connections.
TIP: FS-1 foot switch
At €9, it's less than it would cost to make it at home. The metal body of the FS-1 is smaller in size, measuring 102 x 67 mm and 22 mm high. The height is further increased by four rubber feet and a rubber tread on the top. I weighed 310 grams (including the cable with connector).
The stated electrical life is 100,000 operations, mechanical up to 10,000,000 operations. Resistance in the open state is 10,000,000 operations and resistance in the closed state is 15 mohm, and it is rated up to 10A/250V. The power cable is 1 meter long.
Práve napájací kábel je asi jediná vec, ktorú bude rádioamatér vyriešiť: napojiť vhodný konektor. Ak by Vám kábel dĺžkou alebo typom nevyhovoval, skúste RG-58. Aj keď je to koaxiálny kábel, tak sa mi mechanicky veľmi osvedčil ako ideálny prepojovací kábel v ham shacku.
I have been using the FS-1 for about 4 years. It is often in difficult conditions in the car. Mud or water on the shoes is no exception. However, the switching is very reliable. Compared to my design, it is higher and the spring is stronger. I also appreciate the strength of the design. So if you are planning
