See pictures for example. Note price is per 1 piston, piston rail not included. Pistons will need to be installed and wired yourself.
These are white LED momentary push buttons that function well as thumb pistons for virtual organs such as hauptwerk.
Lettering is applied inside switch cap, so doesn't rub off with constant use.
Similar to thumb pistons used on hauptwerk organs by CONTENT, MIXTUUR and NOORLANDER.
£5 for each piston. Excellent value for money considering most thumb pistons cost £12-15 each from Kimber Allen, P&S, Klann, Syndyne etc, plus the cost of engraving.
Please specify which lettering you require such as + - 0 1 2 3 4 5 6 7 8 9 etc
4 terminals on the rear for switch contacts and +- for LED power.
LEDs draw about 20mA each. 3V max.
I have successfully powered my own pistons (see pictures) through arduino/teensy as midi encoder/decoder.
