Why is it preferable to use a push button
switch for door bells and not an on/off
switch?​

Answer 1

please follow and mark as brainliest

Door bells are meant to be operated intermittently and not supposed to be continuously on. Most of the old door bells have electromagnets that gets energised and actuate a hammer and hit a gong. After hitting it stays there till the circuit is de-energised. After releasing the power switch , the hammer comes back to normal position and hit back in its metal rest or another gong. Thats how that Ting Dong sound came. Nowadays we have a inbuilt make break switch or simply the bell is electronic and it will be a nuisance if the switch is pressed continuous -as correctly said in the previous response.
