The procedure of selecting the correct switch can be summarized this way:
The requirements of the end user should be given consideration first
The engineering aspects like load, contact materials, terminal type, voltage, circuit Read more [...]
We've been selling a lot of this one particular switch - it's called a long travel tact switch; manufactured by ALPS.
Here are some of the features of this switch:
-- Dimensions: 8mm x 8mm
-- Suitable for automotive applications due to its high operational force
-- Malfunctions are prevented due to it having a longer travel than most conventional tact switches
-- Easily mounted on a PC board with snap in leads
-- Some of the output terminals can be used as jumper leads which makes the circuit Read more [...]
