I've been thinking of using a microswitch in a project of mine. The switch should indicate when something is hit. However the thing is the voltage requirements I've seen for most of them are really high compared to the rest of what I'm using, as in I'm getting requirements of of over 100 volts of either direct or alternating current while the sensors and motors (which seem much more complicated and voltage consuming to me) require far less I also remember reading somewhere that the voltage listed on the switches was mainly an upper limit and lower voltages could work. Is this correct? If not, what are are good suggestions for cheap low voltage and current alternatives?
