Solid state touch switch |
摘要 |
A solid state touch switch is provided, in which, during use, a portion of the user's body, such as a finger, forms a portion of an electronic circuit to change the state of a solid state electronic device and thereby actuate the solid state touch switch. Alternative embodiments of the invention contemplate the use of various solid state electronic devices including metal-oxide semiconductor field-effect transistors (MOSFET'S) junction field effect transistors, silicon controlled rectifiers and NPN transistors. One application of the solid state touch switch is in a digital watch in which a user touches a contact pad located on the watch case and thereby turns the digital watch on for the display of time and date signals.
