Beefing up 1/4 inch socket switches

Mar 21, 2008 2 Replies

The third amp in 3 days all requiring attention to quarter inch sockets of one sort or another. Can anyone put a generic or maker's name to this compact axial type

no info of any sort on the socket. This one from an Ashdown effects return with dodgy bypass switch. There are 2 places in the plastic body that drilling through coincides with holes in the metalwork almost as though designed to wrap some silicone rubber cordage (blue in pics) around the switches to increase the closure force, located in place by curves in the contact parts. Then cleaning the contacts. Tip contact to the left and ring contact at bottom of first image.

Incidently my test for whether such bypass switches need attention , even before dismantling the amp. Take one cocktail stick/toothpick . Hold at one end between thumb and index finger and poke the other end in the socket - if the contact breaks before the cocktail stick breaks ,about 150 gms over length of 65mm.

It is AIUI originally a Switchcraft pattern but is very widely copied by Asian suppliers. JAE ?? comes to mind from the dark recesses of my mind.
