Single button telephone dialers are relatively very
cheap devices that are ideal to dial a number but these do not have the capability to
convey any message. These are useful for leaving with children or the baby-sitter or maid
or the old people with the number where you can be reached.
These small gadgets are just put on the mouthpiece of the phone and by pressing the button
the stored telephone number gets dialed automatically. Yes, these do not require any
electrical connection and are quite cheap. |
