In the mixer tap in the bathroom sometimes breaks the pin on the shower switch cold-hot water. In the store it is almost impossible to find, and a new faucet is expensive. It is fixable.
To begin, remove the switch, then from the stock — the two rings of the seal. Take out the axle with a pin. Take the cut copper wire with a diameter of 5 — 6 mm from one end replusive her. Drilling a hole at flattened end and in the center axis for thread M3 (drill diameter 2.5 mm). Made item subtended with the axis of the screw made of brass, bronze, and then collect the switch. It is important not to forget to put back on the stock rubber ring seals.
Recovery switch:
1 — switch, 2 — pin switch, 3 — axis switch, 4 — way stock switch, 5 — sealing ring; 6 — pin-substitute wire, 7 cuff stock.
I use reinstalled the switch about a year.
