Section 3 - Applications
Push-button
The common push-button switch may be rep;aced with a Hall IC and magnet, as shown in two configu-
rations, Figure 17. The slide-by case, Figure 17A, requires a mechanical return spring, returning the push
button after it is depressed, but Figure 17B uses repelling magnets to activate the switch and return the
push-button.
