Abstract
The switch is mounted on a cantilever spring which has a contact that can be positioned over and engage individual contacts of a large bank of contacts. A device is mounted on the spring so as to be responsive to forces either electrostatic, magnetic, gas or liquid pressure. These forces selectively select one of the contacts of the bank of contacts.
